TL;DR
This paper investigates the X-ray spectra of 3d metals in Heusler alloys and La-Sm compounds to understand their electronic and magnetic properties, focusing on Mn spectra and electron localization.
Contribution
It provides experimental X-ray spectra data for specific Mn-based compounds and analyzes the relation between spectral features and electron localization and magnetic moments.
Findings
Spectral features reflect the localization degree of 3d electrons.
Mn spectra indicate the local magnetic moments at Mn sites.
Differences in spectra correlate with alloy composition and electron localization.
Abstract
The Mn x-ray emission spectra and x-ray photoemission spectra of Mn-based Heusler alloys CoMnAl, CoMnSb and LaSmMnSi compounds (x=0, 0.8) have been measured and discussed in connection with a value local magnetic moment at Mn site. The spectra peculiarities reflect also the localization degree of 3d valence electrons of 3d metals in considered compounds.
