摘要
从实验、理论和应用等方面对尖晶石结构材料的最新研究进展进行了总结,对有待进一步开展的研究进行了分析和展望。尖晶石结构材料是新型功能材料的重要组成,在介电、磁性、敏感、发光、超导等功能材料中占据重要地位,并极具应用潜力。尤其是尖晶石结构半金属材料因居里温度高、性能稳定、室温自旋极化率大等优点而被认为是最具应用潜力的自旋电子材料之一,它在计算机读写磁头、磁静态随机存储器、磁性传感器、自旋晶体管等自旋电子器件中极具应用潜力。
The recent advancement in research on spinel structural materials is concluded in system from experi ments, theories and applications. Then the necessary research themes are analyzed and forecasted. Spinel structural materials are very important functional materials including dielectric, magnetic, sensitive, luminescent and supercon- ductive materials. Especially, spinel half-metal materials have high Curie temperature, stable physical properties, and large room-temperature spin-polarization so that they have huge potential application in many areas including read-write magnetic head of computers, magnetic static-state random memorizer, magnetic sensors and spin transistors.
