Abstract

Big changes in resistivity along with the changing of local structure in some oxide systems, such as high-temperature superconductors and colossal magnetoresistance system, strongly suggest the need of a systematic investigation of their local electronic and atomic structures. In this work we present the high-resolution X-ray emission spectra and the spin-polarized X-ray absorption near-edge spectroscopy (SPXANES) data at the Mn K-edge in the La1-xSrxMnO3. This experiment is based on a high-resolution large-acceptance crystal analyzer based on Si (1 1 1) and optimized for X-ray fluorescence spectroscopy. With a spherical bent crystal monochromator, a Mn Kβ emission spectra with high resolution was obtained with a short collection time and SPXANES spectra of La1-xSrxMnO3 at room temperature were also measured at high temperature. © 2008 Elsevier B.V.
