Abstract

A laboratory hard X-ray photoelectron spectroscopy (HXPS) system equipped with a monochromatic Cr K $α$ ( $h ν = 5414.7$ eV) X-ray source was applied to an investigation of the core-level electronic structure of La $_{1 - x}$ Sr $_{x}$ MnO $_{3}$ . No appreciable high binding-energy shoulder in the O $1 s$ HXPS spectra were observed while an enhanced low binding-energy shoulder structure in the Mn $2 p_{3/2}$ HXPS spectra were observed, both of which are manifestation of high bulk sensitivity. Such high bulk sensitivity enabled us to track the Mn $2 p_{3/2}$ shoulder structure in the full range of $x$ , giving us a new insight into the binding-energy shift of the Mn $2 p_{3/2}$ core level. Comparisons with the results using the conventional laboratory XPS ( $h ν = 1486.6$ eV) as well as those using a synchrotron radiation source ( $h ν = 7939.9$ eV) demonstrate that HXPS is a powerful and convenient tool to analyze the bulk electronic structure of a host of different compounds.
