9806308 Adenwalla This research project will investigate the size, shape and spacing dependence of regular arrays of micron sized magnetic features, multilayer features, and measure the coupling between them. The magnetization of these arrays will be studied using conventional magnetic measurements which will give information about the overall bulk magnetization properties, and will also include in-situ Magneto-optical Kerr Effect (MOKE) measurements which provide information during sample growth as well as information about the magnetic correlations between features. With a high resolution MOKE set up it will be possible to study the magnetization feature by feature. Greater understanding of magnetic properties of these arrays and by extension the effects of size, shape and spacing on magnetic properties in general is anticipated. %%% This is a research enhancement grant made under the Professional Opportunities for Women in Research and Education (POWRE) program. The research will contribute new materials science knowledge at a fundamental level.

本研究项目将研究微米级磁性特征、多层磁性特征的规则阵列的尺寸、形状和间距依赖关系，并测量它们之间的耦合。这些阵列的磁化将使用传统的磁测量来研究，这将提供有关整体磁化特性的信息，并且还将包括原位磁光克尔效应（MOKE）测量，该测量提供样品生长过程中的信息以及有关特征之间磁相关性的信息。有了高分辨率的MOKE装置，就有可能逐个研究磁化特征。期望对这些阵列的磁性能有更深入的了解，进而进一步了解尺寸、形状和间距对磁性能的影响。这是在研究和教育领域妇女专业机会（POWRE）计划下提供的一项研究加强补助金。该研究将在基础水平上贡献新的材料科学知识。
