Transport and magnetic properties of the annealed melt-spun Cu₉₀Co₁₀ granular alloy were investigated at elevated temperatures. Complex intrinsie structure of the sample manifests itself in the observed giant magnetoresistance (GMR) characteristics. It is shown that the measured field and teperature dependencies of GMR are strongly influenced by the distribution of the size of superparamagnetic particles and by the presence of the residsual ferromagnetic phase ( much larger particles or agglomerations of smaller particles).
