巨磁电阻效应

1988年阿尔贝•费尔和彼得•格林贝格尔发现，在铁、铬相间的三层复合膜电阻中，微弱的磁场可以导致电阻大小的急剧变化，这种现象被命名为“巨磁电阻效应”．

更多的实验发现，并非任意两种不同种金属相间的三层膜都具有“巨磁电阻效应”．组成三层膜的两种金属中，有一种是铁、钴、镍这三种容易被磁化的金属中的一种，另一种是不易被磁化的其他金属，才可能产生“巨磁电阻效应”．

进一步研究表明，“巨磁电阻效应”只发生在膜层的厚度为特定值时．用R₀表示未加磁场时的电阻，R表示加入磁场后的电阻，科学家测得铁、铬组成的复合膜R与R₀之比与膜层厚度d（三层膜厚度均相同）的关系如图所示。

1994年IBM公司根据“巨磁电阻效应”原理，研制出“新型读出磁头”，将磁场对复合膜阻值的影响转换成电流的变化来读取信息．
