Abstract
Magnetisation and AC susceptibility measurements have been performed to cha racterize the melt-spun Cu97.5Co2.5 alloy. The magnetisation curve, at room temperature, shows two contributions, one superparamagnetic and the other nearly paramagnetic. The temperature dependence of the in-phase AC suscepti bility shows two maxima with different dynamical character. These two anoma lies are ascribed to be superparamagnetic blocking and spin-glass freezing and agree with previous magnetic and structural studies of the same alloy s ystem.
