Engineering Research Equipment: Non-Linear Magneto-Optical Kerr Effect

9617352 Bennett乔治华盛顿大学工程与应用科学学院电气工程与计算机科学系磁学研究所将购买磁光设备，用于支持研究和教育。该设备将用于几个研究项目，包括：与乔治华盛顿大学工程与应用科学学院土木、机械和环境工程系合作，研究磁性多层和纳米复合材料的线性和非线性磁光特性的项目。利用磁光克尔效应，通过测量这些材料表面磁性层的主、小磁滞回线来分析这些多层和复合材料的磁化过程，这是我们的矢量振动样品磁强计无法测量的。这种磁光设备将用于研究现代基于preisach的磁化过程模型的性质。当在扫描模式下使用时，该设备将允许在亚毫米尺度上与使用我们的微磁模型计算的磁化模式进行直接比较。一项利用该设备作为高级本科实验室电气工程课程的一部分的项目，以及一项高级研究项目。＊＊＊

9617352 Bennett The Institute for Magnetics Research, Department of Electrical Engineering and Computer Science, School of Engineering and Applied Science at The George Washington University will purchase magneto-optical equipment which will be dedicated to support research and education. The equipment will be used for several research projects, including: A project to investigate linear and nonlinear magneto-optical properties of magnetic multilayers and nanocomposites, in collaboration with the Civil, Mechanical, and Environmental Engineering Department in the School of Engineering and Applied Science at The George Washington University. A project to utilize the magneto-optical Kerr effect to analyze the magnetizing processes of such multilayers and composite materials by measuring the major and minor hysteresis loops of the surface magnetic layer of such materials that cannot be measured with our vector vibrating sample magnetometer. This magneto-optical equipment will be used to investigate the properties of modern Preisach-based models of the magnetization process. When used in a scanning mode, this equipment will permit direct comparisons of the magnetization pattern on the submillmeter scale with that computed using our micromagnetic models. A project to utilize this equipment as a part of an advanced undergraduate laboratory electrical engineering course, and for a senior research project. ***
