Hello all,

I am trying to do simple ground state ferromagnetic and
antiferromagnetic calculations on metal-diluted materials.

I have read the ABINIT documentation (including the tutorial

on spins) and could not find an example. I'd just

like to make sure that my input file (below), especially
on spinat/nsppol/nspden variables, is correct.

 

Would any of you that had an experience on this kind of

a system give me a comment. I really appreciate it.
Thanks.

ps: Here is a part of my input file. In this case I have 8 atoms

of ZB GaAs in a supercell and I would like to substitute 2

atoms of Ga with 2 atoms of Mn.
