Effect of orbital fluctuations on magnetic properties of -electron systems

Hotta, Takashi

In order to understand magnetic properties of filled skutterudite materials, we evaluate magnetic susceptibility of the Anderson model with orbital degeneracy by using the numerical renormalization group method. Even when the local ground state is , magnetic fluctuations significantly remain, if $Gamma_4^{(2)}$ is the excited state with small excitation energy, as experimentally proposed for Pr-based filled skutterudite compounds.
