Physical Science of Materials


The effect of an applied dc inhomogeneous magnetic field on the structure and the composition of granular Co-Cu films is studied during their deposition by an ion-plasma method and during low-temperature vacuum annealing. Magnetomigration, which consists in the oppositely directed mass transfer of paramagnetic and diamagnetic phases, is detected in both cases. The magnetomigration effect is clearly detected at a temperature of 200–220°C and an applied magnetic field of 500–550 Oe due to a fine-grained structure of the films and, correspondingly, a high granular medium mobility.
