摘要：

The magnetisation of melt-spun, granular Cu100-xCox (x = 5, 15) was measured at room temperature on as-cast and Joule-heated samples. The particle size distribution and the volume density of Co clusters were obtained by fitting the anhysteretic magnetisation curves with four Langevin functions, corresponding to Co particles of definite radii.
