CAREER: Surface and Interface Properties of Antiferromagnetic Heterostructures

9734051莱德曼这是给EPSCoR获奖者的职业奖。模型反铁磁体将被用来研究人工异质结构的表面和界面磁激发以及表面磁有序现象。人们对这些材料非常感兴趣，因为它们具有简单的结构，因此可以从理论上理解它们，并通过计算机模拟它们的行为。这些结果将大大有助于我们对低维磁系统的基本理解，并将被用来理解具有重要技术应用的更复杂的系统。一种新的波导-薄膜光谱学将被用来探测磁激发。关于反铁磁表面长程有序的附加信息将从铁磁覆盖层的磁测量和中子反射率测量中获得。这项提议的教育目标是在西弗吉尼亚州发展科学推广和招生计划，为学生为21世纪以技术为基础的经济做好准备。该项目的教育部分将由三部分组成：1)将协作和实践活动整合到西弗吉尼亚大学的物理课程中；2)参与西弗吉尼亚州的科学推广和招聘计划；3)让本科生直接参与研究计划。%这是对EPSCoR授权者的职业奖励。本项目的研究目标是研究模型磁性材料界面的磁性。人们对这些材料非常感兴趣，因为它们具有简单的结构，因此可以从理论上理解它们，并通过计算机模拟它们的行为。这些结果将大大有助于我们对超小型磁体的基本理解，并将被用来理解在磁存储和磁传感器应用中具有重要应用的更复杂的系统。这项提议的教育目标是在西弗吉尼亚州发展科学推广和招生计划，为学生为21世纪以技术为基础的经济做好准备。该项目的教育部分将由三部分组成：1)将协作和实践活动整合到西弗吉尼亚大学的物理课程中；2)参与西弗吉尼亚州的科学推广和招聘计划；3)让本科生直接参与研究计划。***

9734051 Lederman This is a CAREER Award to an EPSCOR grantee. Model antiferromagnets will be used to study surface and interface magnetic excitations and surface magnetic ordering phenomena of artificial heterostructures. There is much interest in these materials because they have simple structures and therefore they can be understood theoretically and their behavior modeled by a computer. The results will significantly contribute to our basic understanding of low-dimensional magnetic systems, and will be used to understand more complex systems that have important technological applications. A novel waveguide-thin-film spectroscopy will be employed to probe the magnetic excitations. Additional information regarding the antiferromagnetic surface long range order will be obtained from magnetic measurements of ferromagnetic overlayers and neutron reflectivity measurements. The educational objective of this proposal is to develop science outreach and recruiting programs in the State of West Virginia to prepare students for the technology-based economy of the twenty- first century. The educational portion of this project will be composed of three parts: 1) integration of collaborative and hands-on activities into the physics curriculum at West Virginia University; 2) participation in science outreach and recruiting programs in the State of West Virginia; and 3) involvement of undergraduate physics students directly in the research program. %%% This is a CAREER Award to an EPSCOR grantee. The research objective of this project is to study the magnetic properties of interfaces between model magnetic materials. There is much interest in these materials because they have simple structures and therefore they can be understood theoretically and their behavior modeled by a computer. The results will significantly contribute to our basic understanding of very small magnets, and will be used to understand more complex systems that have important applications in magnetic storage and magnetic sensor applications.
