Magnons Dispersion Relation

  1. Jul 13, 2012 #1

    Can anyone explain to me why, concept wise (not from calculations that I get it), is the dispersion relation of magnons (spin waves) quadratic in [itex]k[/itex] for small wavelengths?

    Also, can you give me other examples where such behavior appears?

    Thank you
