摘要：
Magnetoresistance effects and interlayer exchange coupling between magnetic layers, have been investigated in [Hf/Fe-Mn/Ni-Fe-Co/Cu/Ni-Fe-Co/Hf] multilayers by varying the thicknesses of the Ni-Fe-Co, Fe-Mn, and Cu layers. When the Fe-Mn layer is thicker than 5.0 nm, it applies a strong exchange-bias field to the neighboring Ni-Fe-Co layer. The multilayers show high magnetoresistance ratios at Cu-layer thicknesses between 2.0 and 3.0 nm, because the interlayer exchange coupling is weak. The interlayer exchange coupling between the two Ni-Fe-Co layers is always ferromagnetic at Cu-layer thicknesses between 0.5 and 5.0 nm.
