9970789 Celinski这是一个实验和理论相结合的项目，它是磁性多层膜的主要兴趣领域。层状磁性材料是目前最感兴趣的，部分是因为它们在磁存储器件中的应用，部分是因为关于薄层结构与它们的磁性之间的关系的基本问题。该项目的重点是界面形态对复合结构的磁性能的影响。这是一个复杂的问题，因为存在许多不同类型的界面，并且结构界面性质可能与磁性界面性质完全不同。本研究将探讨Fe/Pd/Fe和Fe/Ag/Fe多层膜的磁性和结构特性。这些可以生长有各种良好的特征接口，并根据生长条件，可以表现出从几纳米到一微米不等的平台宽度。一个关键的测量工具是使用铁磁共振，通过测量线宽来确定磁界面质量。结果的一个重要应用将是相关的磁性和结构界面质量与层状材料中的巨磁电阻的大小。这项研究将在一个主要的本科院校进行。参与该项目的学生将接受最先进仪器的优秀培训，为他们在工业界的职业生涯或在研究生院水平上继续研究做好准备。%该研究项目将在一个主要的本科院校进行，并涉及实验学家和理论家之间的密切合作。主要研究人员将研究磁性金属多层膜，巨磁阻效应（GMR）现在商业上用于计算机硬盘驱动器。目的是了解金属多层膜的结构形态如何影响其磁性能。参加该项目的学生接受最先进仪器的优秀培训，为他们在工业界的职业生涯或在研究生院水平的继续研究做好准备。

9970789CelinskiThis is a combined experiment and theory project which an area of major interest in magnetic multilayers. Layered magnetic materials are of great current interest in part because of their applications in magnetic storage devices, and in part because of fundamental questions about the relation between the structure of the thin layers and their magnetic properties. The project focuses on the influence of interface morphology on the magnetic properties of the composite structure. This is a complex problem because there are many different types of interfaces and the structural interface properties may be quite different from the magnetic interface properties. The research will investigate the magnetic and structural properties of Fe/Pd/Fe and Fe/Ag/Fe multilayers. These can be grown with a variety of well-characterized interfaces, and depending on growth conditions can exhibit terrace widths varying from a few nanometers to a micron. A key measurement tool is the use of ferromagnetic resonance to determine magnetic interface quality through measurements of the linewidth. An important application of the results will be to correlate magnetic and structural interface quality with the size of the giant magnetoresistance in the layered materials. This research will be carried out at a primarily undergraduate institution. Students participating in the project receive excellent training with state of the art instrumentation, which prepares them for careers in industry or for continued research at the graduate school level.%%%The research project will be conducted at a primarily undergraduate institution and involves the synergist collaboration between an experimentalist and a theorist. The principle investigators will study magnetic metal multilayers which the giant magneto resistance effect (GMR) now commercially employed in computer hard drives. The objective is to learn how the structural morphology of the metal multilayers influences their magnetic properties. Students participating in the project receive excellent training with state of the art instrumentation, which prepares them for careers in industry or for continued research at the graduate school level.***
