技术摘要：该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。磁光克尔效应（MOKE）是研究磁控溅射沉积过程中薄膜和多层膜的尺寸效应、表面和界面的重要工具。该项目旨在开发一种仪器，该仪器将提供在受控环境下生长和表征材料的能力，这是对多功能材料，多铁性材料和填充碳纳米管的光学，电子和磁性的关键和基本理解的理想选择。拟议的仪器将由摩根州立大学物理系开发和操作。这一工具将用于加强外展方案，以确保少数民族学生获得最大的培训和研究机会。该提案的独特之处在于，将在布鲁克海文国家实验室的国家同步加速器光源中使用先进的x射线技术，如x射线磁圆二色性和x射线元素测绘光谱，进一步研究用MOKE原位和非原位制备和研究的感兴趣样品。概要：本奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。磁光克尔效应（MOKE）用于材料的制备室，是控制材料磁性的不可或缺的工具，有助于推进下一代个人计算机的超高密度数据存储等技术，以及开发快速、小型化和可靠的电子设备。该项目旨在开发一种仪器，该仪器将提供在受控环境下生长和表征材料的能力，这是对所有科学和技术领域有用的材料的光学，电子和磁性进行关键和基本理解的理想选择。拟议的仪器将由摩根州立大学物理系开发和操作。这一工具将用于加强外展方案，以确保少数民族学生获得最大的培训和研究机会。该提案的独特之处在于，利用MOKE原位和非原位制备和研究的材料将在布鲁克海文国家实验室的国家同步加速器光源中使用先进的x射线技术进行进一步研究。

Technical Summary: This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). Magneto-optics Kerr effect (MOKE) for in-situ dynamic studies is an indispensable tool to probe size effects, surfaces, and interfaces of thin films and multi-layers during deposition by magnetron sputtering. This project aims to develop an instrument that will provide the capability to grow and characterize materials under controlled environment which is ideal to gain critical and fundamental understanding of optical, electronic, and magnetic properties of multifunctional materials, multiferroic materials, and filled carbon nanotubes. The proposed instrument will be developed and operated out of the Department of Physics at Morgan State University. This instrument will be used to enhance outreach programs to assure the maximum opportunity for training and research by minority students. The Unique aspect of this proposal is samples of interest prepared and studied with MOKE in-situ and ex-situ will further be studied using advanced x-ray techniques such as x-ray magnetic circular dichroism and x-ray element mapping spectrometry at the National Synchrotron Light Source of the Brookhaven National Laboratory.Layman Summary: This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).
