[Wien] How to determine magnetic configuration
Dear Prof. Blaha and Wien2k Users My aim is to calculated case of MnF2 which has antiferromagnetic configuration. I have defined struct file using Cmmm space group to distinguish Mn atoms and set initial configuration in case.inst file (I have flipped spins for one Mn to get antiferromagnetism) but my results strongly depends on this initial configuration (if I set e.g. the same spin for both Mn atoms, at the end I will get the results as it will be ferromagnetic, and total energy is non higher than for afm). So my question is: should I know exactly magnetic configuration of my case at the beginning or it may be determine during scf cycle (and I am doing something wrong)? Thanks in advance Maciej Pylak
