The magnetic properties of granular Cu-Co alloys produced by melt-spinning have been investigated by DC and AC susceptibility measurements. The results indicate the occurrence of blocking processes of interacting superparamagnetic particles. The effects of annealing by Joule heating at different current densities are discussed in relation to the giant magnetoresistance properties of the system.

Abstract

The magnetic properties of granular Cu-Co alloys produced by melt-spinning have been investigated by DC and AC susceptibility measurements. The results indicate the occurrence of blocking processes of interacting superparamagnetic particles. The effects of annealing by Joule heating at different current densities are discussed in relation to the giant magnetoresistance properties of the system.
