In 2x2x2 supercell, total no. of atoms was 24 and it gave EFG value
6.5 10**21V/m**2
with eta 0.81.
I have also calculated for 3x3x2 supercell has 48 atoms and it gave EFG
value 6.3 10**21V/m**2 with eta 0.88
While experimental is about EFG is 4.4 with eta 0.60..

Dear Gavin Sir,
I got the point.
Thank you very much.
Thanking you.

Dear Wien2k,
I am trying to get the DOS for a system which i included -so and -orb.
My scf calculation successfully completed with "runsp_lapw -so -orb -ec
0.01 -p".
I tried "x lapw2 -qtl -so -orb -up -p". It is ended with an error
"ERROR: -qtl and -orb switches are not compatible
Unmatched
Most importantly: You talked about a 2x2x2 supercell ???
We don't know how big your original cell was, but a 16 atome cell with 1
T is not an impurity as measured in PAC.
How many atoms are in this supercell ???
You must probably increase the supercell size and check convergence of
the EFG.
Thanks for your valuable suggestion, Stefaan sir.

If the goal is to have a EFG that is a predictive as possible for experiment,
then it is advised to take the experimental cell parameters (but with position
optimization).
If that EFG does not agree with experiment, then this is a trigger to search
further. There can be many reasons (assuming
atomic positions optimization means force relaxation.. I have did that.
but I am asking about cell parameter optimization. Is it necessary for .cif
file getting form COD??
Thanks

Yes, optimization of the atomic positions is absolutely necessary to have a
meaningful value for Vzz and eta in a supercell.

Hi Wien2k users,
I am doing EFG calculation for TiNi monoclinic phase, but I am getting
large difference in Calculated and measured value, I have taken parameters
from COD, then make 2x2x2 supercell and replace one Ti with Ta atom... is
structural optimization is necessary?? and eta value was
10 matches
