9601825 Tsui A superconducting quantum interference device (SQUID) magnetometer will be acquired by the University of North Carolina at Chapel Hill. The magnetometer will be used to study the static and dynamic response of metallic and oxide thin films and superlattices. Four types of materials will be studies: metallic thin films and superlattices, high temperature superconducting films, thin films of metallic glasses, and nanostructures made by scanning probe microscopy techniques. The SQUID will be used to investigate magnetic phases, magnetic coupling and magnetotransport in metallic superlattices, effects of oxygen content in high temperature superconductors, electronic states and ordering in metallic glasses, and spin fluctuations and electron-electron interactions in nanostructures. %%% This research will help to elucidate the role of morphology and dimensionality on the material properties and to understand the nature of the magnetic and electronic interactions in these materials. Placement of the SQUID magnetometer in the Research Triangle Park area will enhance the local research infrastructure. ***

9601825 Tsui 北卡罗来纳大学教堂山分校将购买超导量子干涉装置 (SQUID) 磁力计。磁力计将用于研究金属和氧化物薄膜以及超晶格的静态和动态响应。将研究四种类型的材料：金属薄膜和超晶格、高温超导薄膜、金属玻璃薄膜以及通过扫描探针显微镜技术制造的纳米结构。 SQUID将用于研究金属超晶格中的磁相、磁耦合和磁输运、高温超导体中氧含量的影响、金属玻璃中的电子态和有序性，以及纳米结构中的自旋波动和电子-电子相互作用。 %%% 这项研究将有助于阐明形态和维度对材料性能的作用，并了解这些材料中磁和电子相互作用的本质。在三角研究园地区放置 SQUID 磁力计将增强当地的研究基础设施。 ***
