Magnetic anisotropy

  1. Jan 6, 2014 #1
    The magnetic anisotropy of a single ion depends upon what factors? How we can compare the magnetic anisotropy of Fe3+ and Mn3+ in octahedral geometry?

    In general it depends on the orbital momentum. For 3d transitions metals there is no unique answer as for a given number of 3d electrons there are several possible spin states, depending on the strength of magnetic interactions and crystal field splitting.
