通过连续沉积Co、Cu、Ni 80 Fe 20 和Cu层制备了由具有不同各向异性的两种磁性成分组成的多层膜。通过施加适度的磁场，两个磁化方向彼此反平行，然后由于自旋相关的电子散射，电阻显着增加。 [Co(30 A)/Cu(50 A)/NiFe(30 A)/Cu(50 A)]×15 中观察到较大的磁阻变化，在 300 K 时为 9.9%。
Multilayers consisting of two magnetic components with different anisotropies were prepared by successively depositing Co, Cu, Ni 80 Fe 20 and Cu layers. By applying a moderate field, the two magnetizations are oriented antiparallel with each other, and then the electric resistance significantly increases due to spin-dependent electron scattering. A large magnetoresistance change, 9.9% at 300 K, was observed in [Co(30 A)/Cu(50 A)/NiFe(30 A)/Cu(50 A)]×15.
