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.

中国科学学院物理学院的戴维·J·塞尔米尔（David J. Sellmyer），内布拉斯加州大学和赵江之间的这项为期两年合作研究奖的目的是研究基于稀有美食和过渡金属的无定形多层磁性膜。 研究人员将集中于物理性质之间的关系，例如磁有序，随机和相干磁各向异性以及这些合金材料的显微镜结构。 将评估同质和非核心玻璃的结构以及这些材料对磁化信息存储的潜力。 这项新建议扩展了根据1985年美国 - 中国合作研究赠款进行的研究。 稀土转移金属基础合金研究是材料科学的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，设计更好的材料。 内布拉斯加州大学和物理研究所同时，将同时进行高场磁化，X射线衍射和电子显微镜测量值。 美国和中国科学家和实验室设施进行这些重要测量的综合努力实现了美国 - 中国计划的主要目标，即通过国际合作来提高科学知识。
