Abstract Electron structure of self-doped La1−xMnO3+δ perovskites is studied with X-ray absorption spectroscopy by measuring the spectra at manganese L-edges and oxygen K-edge, and analyzing the results for Mn K-edge spectra and magnetization data. The observed change of Curie temperature is explained by the change of level of hybridization of Mn 3d states and the O 2p states, which was manifested by the parallel change of 2p3/2 and 2p1/2 spectra with x and TC.

自掺杂 La 1- x MnO 3+δ (0≤ x ≤0.15) 钙钛矿的电子态和磁性能的杂化：XANES 研究

摘要 通过测量锰L 边和氧K 边的光谱，并分析Mn K 边光谱和磁化数据的结果，利用X 射线吸收光谱研究了自掺杂La1−xMnO3+δ 钙钛矿的电子结构。观察到的居里温度的变化可以通过 Mn 3d 态和 O 2p 态的杂化水平的变化来解释，这表现为 2p3/2 和 2p1/2 光谱与 x 和 TC 的平行变化。
