In case no one has answered this up to now:
ad 1) The procedure itself is ok. You might want switch on SO first and
converge that without the orbital potential to establish a zero-field
base line. Remember to put in LARGE fields - your off-the-shelf lab
field of 10 T will not show up at any energy precision you can achieve.
Estimate the energy of 1 mu_B in 10 T field in Ry units to see that.
Note that your not-so-recent version of Wien2k is not the best for the
task. The latest version is 17.1. With 16.1 came the NMR package which
should be much better suited to calculate the effects of a magnetic
field.
ad 2) If you apply a magnetic field experimentally in the lab you do it
at all atoms. I suppose you want to model that situation. imho it makes
little sense to exempt one or two of your atoms from the field.
Good luck

Dear professor Blaha and WIEN2K users
I'm running WIEN2K of 14 version on Linux system. I'm going to impose
external magnetic field on LaPtBi, a no-magnetic material. The
procedure that I'm going to use is :
1、Do a no-SO calculation : runsp_c_lapw.
2、Do a SO calculation : runsp_c_lapw -so -orb, while including
external magnetic field as orbital potential in the same time.
My questions are:
1、Whether this procedure is OK ? If it is not OK, what is the right
one ?
2、Which atoms and which orbitals should I treat with orbital
potential ? The electron configurations of these 3 atoms are: La (5d1
6s2) ; Pt (4f14 5d9 6s1); Bi (4f14 5d10 6s2 6p3).
Thanks very much for your attention.
Sincerely yours,
Bingrui Peng
