[Wien] Reg: Angle (Theta)dependent dHvA frequencies with SKEAF code

2020-05-20 Thread Peram sreenivasa reddy
Dear Rourke,

Is it possible to calculate angle dependent dHvA frequencies with SKEAF
code.

At the time of initialization of calculation it tis taking default Theta as
zero degree. I need to get the frequencies from 0 degree to 90 degree in
step of 10 degree. Is it possible?

Thanking you.

Dear Peter Blaha and Gavin Abo,

Thank you very much for your help.

With your suggestions and modifications, now the code is writing the all
the values in the case.outputirup and case.outputirdn files.

Once again thank you very much for the support.


Thanking you.

Re: [Wien] Reg: Error in irrep step in FM case

2019-10-15 Thread Peram sreenivasa reddy
Dear Gavin Abo,
Thank you very much for your replay.

I am using WIEN2k_18.2 (Release 17/7/2018).

>From the grep command the system is symmorphic. The out of the "grep PGBSYM
*" is given below.

FM.outputs: PGBSYM: ORDER OF LATTICE SPACE GROUP (WITH BASE) =  12
FM.outputs: PGBSYM: SPACE GROUP IS SYMMORPHIC
FM.outputs: PGBSYM: SPACE GROUP CONTAINS INVERSION

For this system i am trying to get the parity values at different high
symmetry points. So, case.outputirup and case.outputirdn files are
important to me.

Please let me know how to overcome the issue.

Thanking you.

[Wien] Reg: Error in running of wannier90 with AFM+SOC+U

2019-03-26 Thread Peram sreenivasa reddy
Dear Wien2k,

I have successfully completed scf, band and dos calculations with AFM+SOC+U.
The flow of commands to initiate the wannier90 calculations are
>   (init_w2w) options: -up -so
> (x) kgen -fbz
> (x) wannier90 -pp
> (x) lapw1 -up -orb -p
> (x) lapw1 -dn -orb -p
> (x) lapwso -up -orb -p
> (x) w2w -up -so -p
> (x) w2w -dn -so -p
> (x) wannier90 -up -so
> (x) -f super w2waddsp
All the steps went fine except (x) wannier90 -up -so, where got
"Exiting...
 super.amn has not the right number of Wannier functions"

error in case.wout file.

Please let me know the flow of commands  for AFM+SOC+U case. I am thinking
the commands flow may be wrong.

Thanking you.

[Wien] Reg: File to get the number of electrons in majority and minority spin cases for d-orbital

2018-03-04 Thread Peram sreenivasa reddy
Dear Wien2K,

I am working on magnetic metallic systems which are having Mn atoms, which
are responsible for magnetic nature in these systems. As these compounds
are metallic in nature the arrived magnetism is due to the itinerant
electrons. Here i just want to know the number of electrons in majority and
minority spin cases separately for Mn-3d orbitals. From the density of
calculations i can find the states for the Mn-3d orbitals. But i want to
calculate the number of electrons. Is there any file to get the information
regarding the number of electrons in each spin case?


Thanking you.

[Wien] Reg: Limit of maximum number of K points to plot Fermi surfaces for different structures

2016-11-10 Thread Peram sreenivasa reddy
Dear Wien2k and XCrySDen,

I am working on FCC compounds (which have four atoms in a unit cell) with
Wien2k code. To get Fermi surface i used 44x 44x 44 K-mesh, which will
create 2168 k points in the Brillouin Zone. With this number of K points, i
get smooth Fermi surfaces.

After this, i created a supercell which is 8 times larger than the initial
one (which have 32 atoms). In this case, i used 10x10x10 k-mesh(overall
1000 points) to get Fermi surface (which gave 516 k points). But i am
getting errors while generating Fermi surfaces. If i do the same
calculations with lesser k points it is not giving any errors, but my Fermi
surfaces are not smooth. Please suggest me how to overcome this problem.

Is there any maximum limit of k-points usage for different structures?
If i want to run with high k-points what i have to do?. Means is there any
file to edit the limit values and re-install the XCrySDen software.

Please suggest a solution.

Thanking you.

Dear Blaha sir,

Thank you very much for your replay.

Here the problem comes in the calculation of <I^2>, square of the
electron-phonon matrix averaged over the Fermi surface. Here my questions
are:

1. To get alone <I^2> value do we need to use the rigid muffin-tin
approximation(RMTA)?
2. Is there any package or code available which can be used the WIEN2k
files as input files?


Thanking you.

2016-05-18 Thread Peram sreenivasa reddy
Dear WIEN2k,

I am working on six cubic metallic systems. I did total energy calculations
with including spin-orbit coupling and without including spin-orbit
coupling. The energy difference between these two type of calculations is
0.70188367 Ry, 0.83293372 Ry, 0.96565226 Ry, 0.8189581 Ry, 0.94934189 Ry
and 1.07940931 Ry.

1. Is it correct to get this amount of energy difference?

2. Is it possible to get the given energy difference with and without
including spin-orbit coupling effect.

3. Please suggest any references where can get energy differece around 1 Ry
unit.


Thanking you.

[Wien] Reg: Error while running band structure SP+SO case in parallel

2015-05-14 Thread Peram sreenivasa reddy
Dear Wien2k,

I am getting error while calculating band structure in spin orbit case for
a magnetic material.
Here are the commands.

For scf calculations i gave the following command
*runsp_lapw -so -ec 0.01 -p*
It completed successfully.

After that i created case.klist_band and i gave Ef value in case.insp file.
Then i try to gave the following commands.


*x lapw1 -band -up -p*

*x lapw1 -band -dn -p*

*x lapwso -band -up -p*

*x lapwso -band -dn -p*

*x irrep -so -up -p*

*x irrep -so -dn -p*

*x spaghetti -so -up -p*


*x spaghetti -so -dn -p*
First i want to know that the series of commands are correct or not for a
magnetic system with including SO case.

when i give *x lapwso -band -up -p* it is giving error as shown bellow.

[Wien] Reg: How to comment on the more interstitial DOS value at the fermi level

2015-01-10 Thread Peram sreenivasa reddy
Dear Wien2k,

I am working on the Heusler compound. My compound is like X2YZ  type. In
the density of states (DOS) calculations i got the values as bellow at the
fermi level.

for total compound (X2YZ)   30.95 (states/Ry)
For X  16.49 (States/Ry)
For Y   4.46 (States/Ry)
For Z0.38 (States/Ry)
for interstitial 9.62 (States/Ry)

  Here my question is that the DOS value from the interstitial region is
more (it is more than Y and Z atoms contribution). How can i comment on
this value?.

Please give suggestions..

Thank you very much in advance.

[Wien] Reg: AFM calculations

2014-05-22 Thread Peram sreenivasa reddy
Dear Wien2K,

I am trying to do AFM calculations. I followed the user
guide to set the AFM calculations. I got some error. Here i am giving the
step by step information.

1. first i run init_lapw up to lstart in magnetic case. After that i copied
my case.struct to case.struct_supergroup.

2. I again run init_lapw in the same magnetic case like bellow.

- do you want to perform an antiferromagnetic calculation ? (N/y)
y
I hope you haveflipped the spin of the AF-atom
   made zero spin for non-magnetic atoms
in case.inst
- do you want to continue or edit case.inst ? (c/e)
c
   afminput(12:03:08)  case.struct_supergroup present
 The super and subgroups are KLASSENGLEICH
 You must specify a translation vector which transforms the
 spin-up into the spin-dn atom (e.g.: 0.5,0.5,0.5 for AFM bcc Cr)!
0.5 0.5 0.5
0.0u 0.0s 3:03.38 0.0% 0+0k 2064+96io 6pf+0w
You can now use runafm_lapw   for scf
BUT  PLEASE  NOTE:  AFMINPUT and CLMCOPY  are NOT WELL TESTED
You must test your results with an unconstraint  runsp_lapw  afterwards
and recheck the rules generated by afminput
init_lapw finished ok

3. After this i run runafm_lapw -ec 0.01. But i got the bellow error.

xx@x:~/x/y//xxx$ runafm_lapw

Dear Prof. Peter Blaha Sir,

Thank you very much for your replay.

These are the QTL lines corresponding to three atoms in my scf file.

:QTL001: 1.0641 2.9326 0.6710 0.0040 0. 0. 0. 0.3444
0.3267 0. 0. 0.
Q-s-low E-s-low   Q-p-low E-p-low   Q-d-low E-d-low   Q-f-low E-f-low

:QTL002: 1.1366 3.0525 0.4388 0.0051 0. 0. 0. 0.2116
0.2272 0. 0. 0.
Q-s-low E-s-low   Q-p-low E-p-low   Q-d-low E-d-low   Q-f-low E-f-low

Q-s-low E-s-low   Q-p-low E-p-low   Q-d-low E-d-low   Q-f-low E-f-low



From these lines how can i know which value is corresponding to which orbital?

In each :QTL i have 12 values. I am thinking that there are like below

:QTL001:  S E-S P E-P D E-D eg E-eg t2g E-t2g F E-F
   here S= s orbital
  E-S= Energy of s orbital   like that for remaining orbitals.

Is it correct?

Can take the these direct values for eg and t2g orbitals?

Please suggest me?

Thanking you.

 The SPIN moment of an atom is calculated as difference of spin-up -
 spin-dn charges.
 While the total SPIN moment is printed :MMIxxx, the contribution from
 different orbitals are not. You get them as the differences of the
 :QTLxxx lines.

 PS: Don't mix this up with orbital moments, which come due to
 spin-orbit interaction

 http://www.mail-archive.com/wien%40zeus.theochem.tuwien.
 ac.at/msg04711.html].

 There are at least two different methods to calculate the Stoner parameter
 [http://theory.mse.cornell.edu/Magnetism.pdf (slide 9)].

 1) For the first method, the Stoner parameter is estimated from the
 equation

 I = delta_ex/m

 where delta_ex is the exchange splitting and m is the total magnetic
 moment per atom [Dissertation titled Theory of Adsorption, Diffusion and
 Spinpolarization of Mn on Si(001) and Si(111) Substrates at
 http://www.diss.fu-berlin.de/diss/servlets/MCRFileNodeServlet/FUDISS_
 derivate_2402/ (Chapter 3, page 43)].

 2)  For the second method, fixed spin moment (FSM) calculations are
 performed [http://www.mail-archive.com/wien%40zeus.theochem.tuwien.
 ac.at/msg04699.html].

 The obtained E versus m data is fitted to a polynomial equation to extract
 I [http://dx.doi.org/10.1103/PhysRevB.74.014416 (page 3),
 http://www.wien2k.at/reg_user/mailing_list/wien-digest.
 archive/summary_2002_II (search keyword stoner for the post by Mazin)].

 Dear WIEN2k,

 Stoner criteria is IN(EF)/= 1.

 In this N(EF) is density of states value at the Fermi level and I is the
 Stoner parameter.

 I want to know how to calculate this Stoner parameter from first
 principles calculations.

 Thank you in advance.

Re: [Wien] Reg: Fixed spin moment calculations

2014-03-31 Thread Peram sreenivasa reddy
Dear Peter Blaha Sir,

Thank you very much for your replay.

For my system there is no experimental or theoretical proof as it is a
magnet. But in my calculations i got minimum energy in magnetic case with
magnetic moment 1.95 bohr magneton.

I want to confirm that this magnetic moment is correct or not. For that i
am using the fsm calculations.

I followed the step 2 procedure and i got the results like as bellow.

Magnetic moment (bohr magneton)   Energy (Ry)
0.0-16590.18461593
0.5-16590.18612148
1.0-16590.18900235
1.5-16590.19082779
1.9-16590.19142097
1.95-16590.19142434
2.0-16590.19141282
2.05-16590.19138454
2.10-16590.19133936
2.5-16590.19027153
3.0-16590.18587074
3.5-16590.17627193
4.0-16590.16408747

this shows with 1.95 magnetic moment i got minimum energy -16590.19142434
Ry.


In my normal scf calculations with runsp_lapw -ec 0.01 command i got
minimum energy -16590.19143942 Ry.


Is this correct?


Please give me suggestions. Is there any another procedure?. If it is
please suggest me.

If i have to add a total energy in M=0. How to add it?.

Thank you very much.

 Step 2) is the correct thing, but at least you should also add a total
 energy for M=0.
 And if the normal runsp calculation gives you the lowest total energy
 compared to all your fsm calculations, this is the proper solution.

 However:   do you know   WHY   you want to make a fsm calculation ?

 The  FSM method is used in 2 cases:
 a) The total energy of more than ONE magnetic/non-magnetic calculations is
 almost identical. You may see this in a normal scf calculation that it
 converges very slowly (or not at all) or the calculations of runsp_c and
 runsp (zero and finite moments) give almost the same energy.
 b) You obtained some solution with runsp, but you want to search for
 another (eg. a high-spin or low-spin) solution. In this case you have to
 estimate what would be the total moment of such an solution and search the
 corresponding M-range.

 For all the values i have to run scf and check the total energy for each

 values. In this plot where i get the minimum energy for a particular fsm
 value, that magnetic moment value i should have to consider.
 Is this correct procedure?

 Please suggest me further.

 I very much doubt that you got the same bands, probably you got very

 Anyway, runfsm uses 2 different fermi-energies for up and dn and you
 should plug in these two fermi energies into case.insp if you want to see
 the enhanced splitting.

 N!

 Please do not change 0.3 to 0.8, and in fact do not change the 0.3 at
 all and do not use -in1ef. I suggest leaving the linearization
 energies alone unless you are really experienced.

 Your problem is almost certainly in the format of your case.inso or
 similar. You should probably attached your struct file and someone
 else can help you.

 N.B.,  -ec 0.01 is not really useful in most cases, I suggest just
 using -ec 0.0001 -cc 0.0001.
