[Wien] How to calculate orbital moment and HFF?

2010-05-06 Thread Bin Shao
Dear all,

I am running wien version 9.2 on a machine of type cluster with operating
system Centos 5.4, fortran compiler ifort and math libraries intel mkl.

The purpose of my calculations in to get quantity orbital moment, HFF of
spin contribution and orbital contribution. For testing, I use a simple case
bcc Fe.

I have read the ref. Notes about spin-orbit and New notes, Hyperfinefield
calculations by P. Novak, Prague and userguider. And I note that in
usergudier

:ORBxx Orbital magnetic moment of atom xx (needs SO calculations and
LAPWDM).
:HFFxx Hyperfine field of atom xx (in kGauss).

So I did a calculation without SO, then did a calculation with SO (by using
initso_lapw) and LAPWDM (manually). Here is the content of my input files:

Fe.inso

WFFIL
 4  1  0  llmax,ipr,kpot
 -10.   1.5   emin,emax (output energy window)
   0.  0.  1. direction of magnetization (lattice vectors)
 0   number of atoms for which RLO is added
 1   -4.97  0.0005  atom number,e-lo,de (case.in1), repeat NX times
 0 0 0 0 0number of atoms for which SO is switch off;
atoms
--

Fe.indm  Fe.indmc
--
-9.

1 1 2
3 3

When the calculation finished, I checked the file of Fe.scf, but did not
find the :ORBxx. And I did not understand that whether the quantity of HFF
from the spin (orbit) contribution can be get by setting RINDEX=3 LSINDEX=3
(RINDEX=3 LSINDEX=5).

Any suggestions will be appriciate. Thank you in advance.

Best regards,

[Wien] How to calculate orbital moment and HFF?

You did it correctly, but looked at the wrong place for the final 
information.

* run a regular scf-cycle (with spin-orbit)
* execute lapwdm for spin-up, with the same options as you see in :log 
for lapw2 (x lapwdm -up +other options)
* finally, look in case.scfdmup where you will find the orbital hff for 
all atoms and orbitals that you requested in case.indmc

Similarly for the dipolar contribution to the hff (with rindex=3 and 
rindex=5).

The label :ORBxxx in case.scf appears only if you do a LDA+U 
calculation, and gives then the same number you could find by lapwdm.

I would say that program consider the sixth line here ( 1   -4.97  0.0005) 
as number of atoms for which SO is switch off, because in line before there 
is 0 atoms for which RLO is added, so next line (atom number,e-lo,de) should 
be omitted. In the given file.inso, spin-orbit for first atom is switshed off.
So, better to take in this way:
--
WFFIL
 4  1  0  llmax,ipr,kpot
 -10.   1.5   emin,emax (output energy window)
   0.  0.  1. direction of magnetization (lattice vectors)
 0   number of atoms for which RLO is added
 0 0 0 0 0number of atoms for which SO is switch off;
atoms

Or I am mistaking?

Dear Lyudmila Dobysheva,

Thank you for your advice.

It's my fault and I adopt your suggestion.
