9601825徐 位于查佩尔山的北卡罗来纳州大学将购置一台超导量子干涉仪。磁力计将用于研究金属和氧化物薄膜和超晶格的静态和动态响应。四种类型的材料将被研究：金属薄膜和超晶格，高温超导薄膜，金属玻璃薄膜，和纳米结构的扫描探针显微镜技术。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涨落和电子-电子相互作用。 本研究将有助于阐明形态和维数对材料性质的作用，并了解这些材料中的磁性和电子相互作用的性质。在三角研究园区放置SQUID磁力计将加强当地的研究基础设施。 ***

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. ***
