Photoemission Electronic States of (Mn_1-xFe_x)₅Si₃

Abstract

The core-level and valence band electronic states studies of single crystalline transition metal silicides (Mn1−xFex)5Si3 (x = 0 and 0.05) by the X-ray and ultraviolet photoemission spectroscopies are reported. The Mn 2p core-level spectra for both compounds were ascribed to the relevant Mn sites in their crystal structure. The valence band spectra were compared with the result of ab-initio band calculations using the tight-binding linear muffin-tin orbital method. It was concluded that the enhancement of the spectral density within the 2 eV binding energy region below the Fermi energy comes from the effect of strongly correlated Mn 3d electrons.

Magnetic Properties of the Mn5Si3Compound

“…The electronic density of states calculated by TB LMTO method was presented in Fig. 5 of paper [22]. For both types of the crystal structure the Mn 3d states form the broad bands near to the Fermi level with the small shift between the states with the different orientation of spins.…”
