Re: [Wien] different MLD for bcc structure for magnetic equivalent directions M001, M010 and M100

Hi Gerhard, I know that due to SO, the electronic structure calculated for 100, 010 and 001 magnetization directions are different. The problem I have is following: I have three calculated electronic structures of bcc Fe, with magnetizations along 001, 010 and 100. Then, for any cubic

I suppose that this does not have to do (much) with centering the mesh. My guess based on other QMO calculations is that some contributions to mat. els. of e.g. vx*vx from different parts of the BZ don't cancel (numerically) even if they actually should. It is instructive to repeat the
