Non-collinear magnetizm
Posted: Wed May 22, 2013 11:15 am
Hi,
We try to calculate non-collinear antiferromagnetic arrangement of olivin structure Mn2GeO4. First, we did test of non-collinear calculations. If we direct spins in x, y or z directions, then total energy must be the same for all these directions and be equal of collinear case. But we obtain that it is true only for ferromagnetic arrangement, but for antiferromagnetic one energy is depend on spin direction, that is physically wrong. Spin-orbital interaction are not included.
Are anybody have some ideas why it is so?
