[Wien] spin-orbit coupling and magnetic anisotropy

[pieper]

Dear community

A question concernig spin-orbit coupling, and from there magnetic
anisotropy: From Pavel Novak's lecture notes on the calculation of
so-coupling in Wien2k I understand that this contribution to the
Hamiltonian is taken into account within the RMT only. Am I correct that,
thereby, Wien2k will only give information on what is termed the single-ion
anisotropy, but NOT on the anisotropic exchange (pseudo-dipolar)
interaction which arises if so-interaction on two neighboring ions is
treated with the Heisenberg exchange interaction as a perturbation? This
anisotropy is, of course, particularly important for spin-1/2 systems like
Cu2+ where the single-ion anisotropy vanishes.

Best regards,

Martin
