摘要：

Magnetoresistance effects have been investigated in spin-valve multilayers including three Ni-Fe-Co layers. The layered structure of the spin-valve multilayers are [AF1/Ni-Fe-Co/Cu/Ni-Fe-Co/Cu/Ni-Fe-Co/AF2/Si], where AF1 and AF2 are antiferromagnetic layers. The spin-valve multilayers including three Ni-Fe-Co layers show magneto-resistance ratios Delta rho/rho of 3.7% and 5.6% at around 1.5 kA/m. These values are higher than the 2.2% of a spin-valve sandwich that includes two Ni-Fe-Co layers, [Ni-Fe-Co/Cu/Ni-Fe-Co/Fe-Mn/Cu/Hf/Si]. It is found that the total resistivity changes (Delta rho) of the spin-valve multilayers including three Ni-Fe-Co layers are twice that for the spin-valve sandwich that includes two Ni-Fe-Co layers. This is due to the fact that the number of Ni-Fe-Co/Cu interfaces in the spin-valve multilayers that include three Ni-Fe-Co layers is double that in the spin-valve sandwich that includes two Ni-Fe-Co layers.
