Transport and Spectroscopic Studies of Narrow Band Materials

计划对窄电子带金属中与中间价、超导性和磁性有关的现象进行研究。加州大学圣地亚哥分校（UCSD）和密歇根大学（UM）之间的联合研究项目将包括在UCSD进行样品制备，表征和体特性测量，以及在UM进行实验室和同步加速器辐射的电子能谱分析。将努力发现和表征具有新颖窄带现象的新材料，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电子结构及其与这些材料新特性的关系。这些信息将用于测试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杂质与安德森哈密顿体系之间的关系。

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.
