Paper Abstract

Metastable CoCu thin films are deposited by rf magneto- sputtering. The relationship between magnetoresistance of CoCu granular films and vacuum annealing temperature, applied magnetic field, composition of alloy thin film are studied. FCC structure Co second phase are precipitated after annealing. Giant magnetoresistance effect is observed in the nonmagnetic Cu matrix, its magnitude depends on the quantity and size of Co particles. The structure of CoCu granular alloy films is investigated by x-ray and TEM method.
