Hi Mutlu, I believe you need to extend the unit cell to the fundamental magnetic lattice, not just the atomic Bravais lattice. You need duplicate the unit cell in one direction and define the Mn in each of the two subcells as different 'species' and treat them accordingly. *Steve Novakov*

[Pw_forum] about antiferromagnetic case

2018-02-12 Thread Mutlu COLAKOGULLARI
Dear Community, I am working on K2MnF6 which has cubic lattice with Fm-3m symmetry (no 225). I have already done non-magnetic (NM) and ferromagnetic (FM) cases. Unfortunately, I have been locked to antiferromagnetic (AFM) case. Let me tell you the little story: its primitive cell has one Mn
