摘要
在概述隧道结巨磁电阻效应及其机理的基础上,综合介绍了多层薄膜结构、微颗粒膜结构和近年来出现的基于多晶隧道结结构的巨磁电阻效应及其相关材料的研究最新进展。重点讨论了涉及隧道结磁电阻材料类型、化学组成、结构与性能、制备技术以及潜在的应用前景,对制备工艺简单、成本低并可能带来突破性发展的多晶隧道结巨磁电阻材料作了展望。
The latest research progress on giant magnetoresistance materials with tunnel junctions, including the multi-layered films, nano-particulate films and polycrystalline bulk materials that have been developed in recent years, are reviewed on the basis of an overview of the tunnel junction magnetoresistance effect and its mechanism. The types of tunnel junction magnetoresistance materials, chemical compositions, microstructural features, magnetoresistive properties, processing techniques and their potential applications are discussed with regard to their favorability as polycrystalline magnetoresistance materials. The polycrystalline magnetoresistance materials with tunnel junctions prepared by using a simple and low cost preparation technique are investigated in order to gain a breakthrough development.
