Antiferromagnet more subblatices

  1. Jun 8, 2013 #1
    In ordinary definition antiferromagnet lattice has to sublattices, one with spins up, and one with of spin down in ##T=0##. Why in some cases people discuss situations with four or even more subblatices? Do you have explanation for this? Some references maybe?

    Do you have specific examples in mind?

    I'm speaking in general. I just see that in some papers some authors uses for example four sublattices for body centered cubic lattice. Why not two? I don't understand this.

    I could speculate about spin waves, or non-collinear antiferromagnetism, or with a non-elemental material there may be multiple magnetic sublattices, or some other situation but without something specific I can't say more than that.

    One example will be enough...
