本文综述了磁电阻(MR) 材料的研究进展,并对目前研究热点的四类巨磁电阻(GMR) 材料进行了概括评述,侧重论述MR 材料在信息存储等领域的应用,明确指出开发和应用MR 材料的关键问题是提高各类GMR 材料的室温MR 值和降低其工作磁场。
【关键词】 MR 材料;各向异性磁电阻(AMR) 效应;GMR 效应;磁电阻随机存储器(MRAM) ;GMR 传感器
【Abstract】 In this paper , the progress in the study of magnetoresistance (MR) materials is reviewed and the presently focused four classes of giant magnetoresistance(GMR) materials , particularly the applications of MR materials in information storage and so on. are dis2 cussed. We clearly point out that the key to exploitation and application of MR materials is to increase the room2temperature MR of GMR materials and decrease the external magnetic field.
【Key words】 magnetoresistance(MR) materials ; anisotropic magnetoresistance (AMR) effect ; giant magnetoresistance (GMR) ef2 fect ; magnetoresistance random access memory(MRAM) ; GMR sensor
