Abstract

Magnetoresistance (MR) properties were studied in Cu/Co/Cu/Ni80Fe20 system, and a large MR ratio was observed in weak external fields. In the course of field sweeping, these two magnetic components (Co and Ni(Fe)) are oriented antiparallel, because of the difference of coercive forces, and then the resistivity is greatly enhanced. The MR ratio was observed to be 10% at 300K, and 32% at 20K, respectively, in a multilayer \Cu(55Å)/ Co(25Å)/Cu(55Å)/Ni80Fe20(25Å)] ×15.
