摘　　要：由于巨磁阻效应材料在磁记录设备和传感器的潜在应用,具有该效应的材料得到了广泛地研究。特别是继金属多层膜之后的金属磁性颗粒膜,由于其制备简单,巨磁阻效应的机理较为复杂,受到人们的青睐。综述了金属磁性颗粒膜中巨磁阻效应的理论。在此基础上,指出了当前值得注意的研究方向。Materials with giant magnetoresistance effect(GMR)have been extensively studied because of their potential applications in magnetic recording and sensors. Especially, there has been great interest in metallic films containing magnetic granules due to their simple preparing method and complicated mechanisms of GMR effect. The theoretical studies of GMR effect are reviewed in this paper. Meanwhile, the development trends of GMR effect are pointed out.
