Dear Wien2k users,<BR>
I have a very confusing a problem. I want to do a AFM calculation of LaOCrAs, and also I inverse the spin up and spin down. <BR>
in LaOCrAs.inst. But the converged result shows that the magnetic moments in the two Cr atoms are spin polarized in the parallel direction,<BR>
rather than in anti-parallel direction(see below), which is totally equivlent to a FM calculation. The similar problems also occured when I try to calculate LaOMnAs, LaOFeAs, etc.The AFM calculations are just carried out by commanding runsp_lapw after I filps the two Cr atoms spins <BR>
and set magnetic moments of non-magnetic atoms to be zero. Did I make some mistakes in these AFM calculation<BR>
<BR>
Any suggestion will be greatly appreciated !<BR>
