项目摘要

The proposed work is intended to deepen our understanding of a novel class artificially-structured, magnetic layered materials, composed of both amorphous and crystalline components. The main thrusts of the work will be: (a) relationships between fundamental microscopic interactions (anisotropy and exchange) and the magnetic properties and spin correlations, (b) relationships between electronic structure, optical, and magneto- optical properties, and (c) studies of the design of magnetic materials with the desired properties. The types of experiments to be performed include x-ray diffraction, electron microscopy, dc magnetization, ac susceptibility, Mossbauer effect, ellipsometry, polar Kerr effect, and small angle neutron scattering (at NIST). In addition to providing information on procedures for producing different types of bilayered and multi- layered magnetic films the research should increase our understanding of: (a) interfacial magnetism and perpendicular anisotropy, (b) fundamental relationships between electronic structure and principles of alloy design based on chemical considerations, and (c) prospects for new magnetic-optic data storage media based on these systems.
拟议的工作旨在加深我们对由无定形和晶体组成的新型类人工结构,磁性层次材料的理解。 作品的主要推力将是:(a)基本微观相互作用(各向异性和交换)与磁性和自旋相关性之间的关系,(b)电子结构,光学和磁性特性与(c)之间的关系研究具有所需特性的磁性材料的设计。 要执行的实验类型包括X射线衍射,电子显微镜,DC磁化,AC易感性,Mossbauer效应,椭圆测量,极性Kerr效应和小角度中子散射(NIST)。 除了提供有关生产不同类型的双层和多层磁性膜的程序的信息外,研究还应增加我们对:(a)界面磁性和垂直方向性各向异性,(b)电子结构与基于合金设计原理之间的基本关系基于这些系统的化学考虑因素以及(c)新的磁性数据存储介质的前景。
