No, Wien2k probably won't 'determine alone which spin state is
energetically more stable'.
States with different spin configurations (PM, FM, AF, ...) frequently
have small differences in total energy but large differences in their
electronic configuration. Due to this the scf cycle tends to
Dear Wien2k users,
I want to know which subroutine calculates gradient and Laplacian of the
density or from where an exchange-correlation functional gets 'grho' and
'g2rho'. A quick reply will be very helpful.

It is not always so simple to find the charge state of an atom. It
really depends on the material you are looking at.
But for Fe 2+ or 3+ in high-spin configuration of some Fe-oxide it is
rather simple:
Fe3+ in high-spin conf. has 3d5-up and no 3d-dn electrons. This makes a
spin-moment of 5
Hallo Abderrahmane,
you find the occupation of the states (INSIDE THE SPERES !) in the
case.scf2up/dn files.
See the lines with e.g.:
:CHA002: TOTAL VALENCE CHARGE INSIDE SPHERE
:PCS002: PARTIAL CHARGES SPHERE = 2 .
:QTL002:
the content should be selfexplaining.
Take care, you

thank you Martin Gerhard Peter and Laurence for the answers
I think the conclusion is as follows:
The high or the low spin configuration of an ion is selected within the
initialization and the best choice is appared in the result as in the case
of Fe2+ ion.
