摘要：

An enhanced magnetoresistance of up to 11% at room temperature has been found in granular Cu1-xCox (0.1 less-than-or-equal-to x less-than-or-equal-to 0.5) alloys, which were prepared by melt-spinning and a subsequent annealing treatment. The rapid solidification extends the solubility of Co in Cu, i.e. the as-quenched state consists of a supersaturated Cu matrix with some quenched-in Co-precipitates. During a subsequent heat treatment, the size and the density of the precipitates can be varied. Since the precipitates behave superparamagnetically at room temperature, the average particle sizes and the amount of precipitated Co can be estimated from magnetization curves.
