On superexchange interaction between orbitally degenerate ions

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The problem of the superexchange interaction between orbitally degenerate ions in magnetic insulators is considered using the tensor operator formalism. The exchange Hamiltonian is derived for ions described in different representations. The number of parameters can be substantially reduced by symmetry considerations and by specifying the exchange mechanism as it is shown on the example of KCoF3.
