Hidden relationship between the electrical conductivity and the Mn 2<i>p</i> core-level photoemission spectra in La1โ<i>x</i>Sr<i>x</i>MnO3
Core-level electronic structure of La1-xSrxMnO3 has been studied by x-ray photoemission spectroscopy (XPS). We first report, by the conventional XPS, the well-screened shoulder structure in Mn 2p3/2 peak, which had been observed only by hard x-ray photoemission spectroscopy so far. Multiple-peak analysis revealed that the Mn4+ spectral weight was not โฆ
