Interface Magnetism and Structure

本研究项目由化学学部分析与表面化学项目和材料学部固体化学项目联合支持，研究磁性表面和界面的几何和电子结构的关键问题。kbanoff教授将开发和应用自旋分辨x射线光电子能谱、光电子衍射和表面扩展电子损失精细结构能谱的方法来表征沉积在表征良好的单晶金属衬底上的磁性活性元素薄膜的磁性。最初的工作将集中在沉积在Fe（100）表面的Cr层的界面磁性上，并将扩展到其他铁磁系统，包括Fe， Co， Ni和Gd。了解磁性活性材料的表面和界面的磁性和结构特性，对磁记录工业和磁性活性电子元件的设计和制造具有极其重要的意义。本研究项目将为磁性活性材料薄层磁性结构的表征开发强有力的新方法，并将其应用于模型系统的研究。从这些研究中获得的信息将为设计和理解磁性表面和界面提供至关重要的数据。

This research project, supported jointly by the Analytical and Surface Chemistry Program of the Chemistry Division and the Solid State Chemistry Program of the Division of Materials Research, addresses key questions of geometric and electronic structure of magnetic surfaces and interfaces. Professor Klebanoff will develop and apply methods of spin resolved X-ray photoelectron spectroscopy, photoelectron diffraction, and surface extended electron loss fine structure spectroscopy to characterize the magnetic properties of thin films of magnetically active elements deposited on well characterized single crystal metal substrates. Initial work will concentrate on the interfacial magnetic properties of Cr layers deposited on the Fe(100) surface, and will be extended to other ferromagnetic systems including Fe, Co, Ni, and Gd. %%% An understanding of the magnetic and structural properties of the surfaces and interfaces of magnetically active materials is of tremendous importance to the magnetic recording industry and to the design and manufacture of magnetically active electronic components. This research program will develop powerful new methods for the characterization of the magnetic structure of thin layers of magnetically active materials, and apply them to the study of model systems. Information obtained from these studies will provide data crucial to the design and understanding of magnetic surfaces and interfaces.
