| 中文摘要 | The change of the orbital angular momentum m(l) of the Cu 3d holes going from the insulating to the metallic phase has been studied in several families of high T(c) superconductors. The symmetry of the 3d9L states in the metallic phase has been studied by quantitative analysis of the variation of polarized Cu L3 x-ray absorption spectra. At a doping level n(h) approximately 15% we have found 10% of Zhang-Rice singlets 3d(x)2-y2L(b1) and 5% of 3d3z2-r2 L(a1) states. Therefore the percentage of the 3d3z2-r2L states on the total number of the 3d9L states is about 30% i.e. much larger than the probability of single hole states 3d3z2-r2 in the insulating phase. The EXAFS and XANES studied of the Cu site structure and dynamics in Bi2Sr2Ca1-xYxCu2O approximately 8 system point toward the coupling of the charge carriers with distortions of the Cu sites driven by the m(l) = 0 character of the Cu 3d holes that can be called a 3d(z)2-r2 polaron. |
