POWRE: Sabbatical Research in Nanostructured Magnetic Materials

9806050 Pardavi-Horvath本项目研究金属-类金属软磁材料和过渡金属-稀土硬磁材料纳米晶和纳米结构材料的材料技术方面。PI将在马德里康普顿斯大学应用磁学研究所度过一段时间。她计划研究离散FFT和Preisach模型的适用性，以表征复合材料中颗粒的统计分布，并建立密切的国际合作，以开发具有可控介电和磁性能的新型磁性纳米复合材料。1999年春，她将访问加州大学圣地亚哥分校的薄膜实验室，在那里她将参与研究超导薄膜上电子束光刻成的磁点阵列的电子特性。她将积极参与二维小磁颗粒阵列与超导衬底的相互作用研究，对相互作用的形状和尺寸效应进行数值计算，以及结构中畴壁涡钉住的来源；此外，她将积极参与加州大学圣地亚哥分校正在进行的磁性多层膜和薄膜的研究。这是在研究和教育领域的女性专业机会（POWRE）项目下提供的访问教授资助。该研究将在基础水平上贡献新的材料科学知识。

9806050 Pardavi-Horvath This project addresses materials technology aspects of metal-metalloid soft magnetic materials, and transition metal-rare-earth hard magnetic materials in nanocrystalline and nanostructured forms. The PI will spend time at the Applied Magnetism Institute of the Complutense University of Madrid. She plans to investigate the applicability of the discrete FFT and Preisach models to characterize the statistical distribution of particles in the composite, and establish a close future international collaboration to develop new magnetic nanocomposites with controlled dielectric and magnetic properties. During the spring of 1999 she will visit the Thin Film Laboratory of the University of California at San Diego where she will participate in the study of electronic properties of an array of magnetic dots patterned by e-beam lithography on superconducting films. She will be actively involved in research on the interactions of a 2D array of small magnetic particles with a superconducting substrate, performing numerical calculations of the shape and size effects on the interactions, and the sources of the domain-wall-vortex pinning in the structure; additionally, she will take an active part in the ongoing research on magnetic multilayers and thin films at UCSD. %%% This is a Visiting Professorship 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.
