Abstract

The cerium monopnictides and monochalcogenides show unusual magnetic behavior associated with the hybridization of f-states with band states of non-f atomic parentage. Previously we have developed understanding of the resulting orbitally-driven magnetic phenomena on the basis of a model (Anderson lattice) hamiltonian with the parameters taken as phenomenological input. We now present a first principles calculation of the parameters in the model Hamiltonian.
