Observation of Hubbard bands in γ-manganese
PACS: 71.15.Qe, 71.20.Be, 79.60.-i
Abstract
We present angle-resolved photoemission spectra of the γ-phase of manganese as well as a theoretical analysis using a recently developed approach that combines density functional and dynamical mean field methods (LDA+DMFT). The comparison of experimental data and theoretical predictions allows us to identify effects of the Coulomb correlations, namely the presence of broad and nondispersive Hubbard bands in this system.
