U.S.-China Cooperative Research (Solid State Physics): Mag- netic Properties and Anisotropy in Rare Earth-Transition Metal Multilayered Films

内布拉斯加州大学的David J.Sellmyer和中国科学院物理研究所赵建高的这项为期两年的合作研究奖的目标是研究基于稀土和过渡金属的非晶态多层磁性薄膜。研究人员将专注于磁有序、随机和相干磁各向异性等物理性质与这些合金材料的微观结构之间的关系。将评估均质和非均质玻璃的结构以及这些材料在磁光信息存储方面的潜力。这项新的建议扩展了1985年美国-中国合作研究基金下进行的研究。稀土过渡金属基合金的研究是材料科学中一个非常活跃和重要的领域。这些合金目前被认为是电子设备和磁性数据存储的最佳候选者。他们的基本理解将有助于改进和更好地设计材料。高场磁化、X射线衍射和电子显微镜测量将在内布拉斯加州大学和物理研究所同时进行。美国和中国的科学家和实验室设施在进行这些重要测量时共同努力，实现了美国-中国计划的主要目标，即通过国际合作促进科学知识的发展。

The objective of this two-year cooperative research award between David J. Sellmyer, University of Nebraska and Zhao Jiangao, Chinese Academy of Sciences' Institute of Physics is to study amorphous multilayered magnetic films based on rare-earths and transition metals. The investigators will concentrate on the relationship between physical properties such as magnetic ordering, random and coherent magnetic anisotropy and the microscopic structure of these alloy materials. The structure of homogenous and inhomogenous glasses and the potential of these materials for magneto-optic information storage will be assessed. This new proposals extends the research performed under a 1985 U.S.-China cooperative research grant. Rare earth-transition metal base alloys research is a very active and important area of materials sciences. These alloys are currently considered to be the best candidates for electronic devices and magnetic data storage. Their fundamental understanding will contribute to improved and better designed materials. High field magnetization, x-ray diffraction and electron microscopy measurements will be performed concurrently at the University of Nebraska and the Institute of Physics. The combined efforts of U.S. and Chinese scientists and laboratory facilities in performing these important measurements fulfills the U.S.-China Program principal objective, which is to advance scientific knowledge through international collaboration.
