Abstract

The electronic structure of pyrite-type MnTe2 has been investigated by photoemission spectroscopy. The Mn 3d partial density of states was obtained from resonance photoemission experiments in the Mn 3p→3d core excitation region. The experimental results were compared with a linear-muffin-tin-orbital atomic-sphere-approximation ab initio calculation, and some discrepancy was found. To reveal a role of electron correlation, the results were analyzed in terms of the configuration-interaction model by considering a (MnTe6)10- cluster, and parameter values for a model Hamiltonian were estimated (U = 5.5 eV, Δ = 1.5 eV and T = 1.4 eV). X-ray photoemission spectra of the Mn 2p core level were also measured to confirm this assignment.
