A program of research directed at the development of new magneto- optical materials and devices is proposed. Improved magneto-optical recording technology and integrated-optical signal processing devices will be pursued. Both amorphous rare earth-transition metal materials and crystalline oxides such as busmuth-containing garnets and cobalt- ferrites would be developed for application in these two technologies. The work on amorphous rare earth-transition metal alloys will be directed primarily at understanding the magneto-optical effect in these materials and thereby at developing materials with larger magneto-optical rotations. An improved understanding of the magnetic anisotropy and coercivity of these materials is also expected to result.

提出了一项旨在开发新型磁光材料和器件的研究计划。 将寻求改进的磁光记录技术和集成光信号处理设备。 非晶态稀土过渡金属材料和晶体氧化物（例如含busmuth的石榴石和钴铁氧体）都将被开发用于这两种技术的应用。 关于非晶态稀土-过渡金属合金的工作将主要致力于了解这些材料中的磁光效应，从而开发具有更大磁光旋转的材料。 预计也会加深对这些材料的磁各向异性和矫顽力的理解。
