Magnetic Moment Creation at Interfaces

这项研究项目由化学部的分析和表面化学计划和材料研究部的固态化学和聚合物计划共同支持，探索外延单分子层和双层的磁性。用自旋分辨光电子能谱研究了沉积在Fe(001)表面上的非磁性金属覆盖层中磁性的产生。用X射线光电子衍射法测定了这些体系的覆盖层几何结构。结合理论计算，这些信息被用来全面检查使用通常非磁性材料创建磁性界面的情况。这些材料的新颖性质是人们最感兴趣的，也与理解磁性薄膜记录材料有关。在分析和表面化学计划以及固态化学和聚合物计划的支持下，利哈伊大学的Klebanoff教授正在研究沉积在磁性铁衬底上的非磁性金属单层和双层薄膜的磁性。来自自旋相关电子能谱的磁性信息与几何信息和理论计算相结合，提供了对这些基本重要的固态系统的详细了解。更好地了解薄膜材料的磁性对于磁记录材料行业的持续健康和发展至关重要。

This research project, supported jointly by the Analytical and Surface Chemistry Program of the Chemistry Division and the Solid State Chemistry and Polymers Program of the Division of Materials Research, explores the magnetic properties of epitaxial monolayers and bilayers. Spin resolved photoelectron spectroscopy is used to probe the creation of magnetism in non-magnetic metallic overlayers deposited on the Fe(001) surface with elemental specificity. X-ray photoelectron diffraction is used to determine overlayer geometric structure in these systems. In combination with theoretical calculations, this information is used to comprehensively examine the creation of magnetic interfaces using normally non-magnetic materials. The novel properties of these materials are of fundamental interest, and are relevant to the understanding of magnetic thin film recording materials. %%% With the support of the Analytical and Surface Chemistry Program and the Solid State Chemistry and Polymers Program, Professor Klebanoff of Lehigh University is investigating the magnetic properties of monolayer and bilayer films of non-magnetic metals deposited on magnetic iron substrates. Magnetic information from spin dependent electron spectroscopy coupled with geometrical information and theoretical calculation, provide a detailed understanding of these fundamentally important solid state systems. A better understanding of the magnetic properties of thin film materials is essential for the continued health and growth of the magnetic recording materials industry.
