【摘要】 根据唯象理论，并采用以铁磁─非磁混合层代替铁磁／非磁层界面的理论方法，计算了Ｆｅ／Ｃｒ多层膜的巨磁电阻随铁磁和非磁层厚度的变化关系与实验结果做了比较，发现它们符合得较好．还绘出了巨磁电阻随铁磁和非磁层厚度变化的二元函数图更多还原

【Abstract】 Based on the phenomenological theory in which the mixed layer composed of the ferro magnetic and nonmagnetic materials is introduced in lieu of the interface, we calculate thedependences of the giant magnetoresistance (GMR) in Fe/Cr multilayers on the thicknessesof ferromagnetic (FM) layers and non-magnetic (NM) layers. Good agreement of the calcu lated resutls with experimental ones is found. The two-variable function of the GMR respect to the thicknesses of FM and NM is plotted.更多还原
