在由坡莫合金(Ni_(80)Fe_(20))和铜组成的多层薄膜材料中,可以发现存在着随铜隔离层的厚度起伏变化的强大的反铁磁耦合以及与此有关的巨磁阻特性。然而,这种特性通常只有在采用溅镀工艺制得的多层薄膜中才能检测到,而由蒸发工艺制得的多层薄膜材料常常不显示出或者只显示出非常微弱的反铁磁耦合以及巨磁阻特性。德国在德累斯顿固态和材料研究所从事这方面研究的
In a multi-layer thin-film material consisting of permalloy (Ni_ (80) Fe_ (20)) and copper, it is found that there is a strong anti-ferromagnetic coupling with the undulation of the thickness of the copper isolation layer and the associated giant Magnetoresistive characteristics. However, this property is usually only detectable in multilayered films made using a sputtering process, whereas multilayer thin film materials made by an evaporation process often do not show or show only very weak antiferromagnetic coupling and Giant magnetoresistive characteristics.
