Transport and Spectroscopic Studies of Narrow Band Materials

计划进行一项研究，以研究具有窄电子能带的金属中与中间价、超导电性和磁性有关的现象。加州大学圣地亚哥分校(UCSD)和密歇根大学(UM)的联合研究项目将包括加州大学圣地亚哥分校和密歇根大学的样品制备、表征和整体性质测量，以及实验室和密歇根大学的同步辐射电子能谱。将努力发现和表征显示新的窄带现象的新材料，特别是高温氧化物超导体和重费米子超导体。将进行光谱测量，以确定这些材料的电子结构及其与新特性的关系。这些信息将被用来检验窄带行为的相关理论，重点是过渡金属化合物的系统学，以及安德森哈密顿量的杂质和晶格制度之间的关系。

An investigation is planned to study the phenomena associated with the intermediate valence, superconductivity, and magnetism in metals with narrow electronic bands. The joint research project between the University of California, San Diego (UCSD) and the University of Michigan (UM) will include sample preparation, characterization, and bulk properties measurements at UCSD and electron spectroscopy, both laboratory and with synchrotron radiation at UM. An effort will be made to discover and characterize new materials that display novel narrow band phenomena, especially high temperature oxide superconductors and heavy Fermion superconductors. Spectroscopic measurements will be made to determine the electronic structure and the relation to the novel properties of these materials. This information will be used to test relevant theories of narrow band behavior, with emphasis on systematics in transition metal compounds and the relation between the impurity and lattice regimes of the Anderson Hamiltonian.
