Temperature-dependent band structure of bulk EuO

Abstract We present calculations for the temperature-dependent electronic structure of bulk ferromagnetic EuO based on a parametrization of the d–f model Hamiltonian using results of first-principles TB-LMTO band-structure calculations. The presented method avoids the problem of double counting of relevant interactions and takes into account the symmetry of the atomic orbitals. It enables us to determine the temperature-dependent band structure of EuO over the entire temperature range.
