| 中文摘要 | Core-level spectra of the Mn-doped Sr(3)Ru(2)O(7) and Sr(n+1)Ru(n)O(3n+1) (n=1, 2, and 3) crystals are investigated with x-ray photoelectron spectroscopy. Doping of Mn to Sr(3)Ru(2)O(7) considerably affects the distribution of core-level spectral weight. The satellite of Ru 3d core levels exhibits a substantial change with doping, indicating an enhanced electron localization across the doping-induced metal-insulator transition. However, the Ru 3p core levels remain identical with Mn doping, thus showing no sign of doping-induced multiple Ru valences. In the Sr(n+1)Ru(n)O(3n+1) (n=1, 2, and 3), the Ru 3d core-level spectra are similar, indicating that the chemical bonding environment around Ru ions remains the same for different layered compounds. While the Sr 3d shallow core levels shift to higher binding energy with increasing n, suggesting their participation in Sr-O bonding with structural evolution. |
