Abstract
Temperature measurements of the anhysteretic magnetization M were performed on nearly-superparamagnetic, granular Cu 90Co 10 submitted to different Joule-heating currents using a VSM. Below about 500 K, the anhysteretic magnetization is fully reversible. All isothermal M( H) curves may be fitted by a superposition of Langevin functions with distributed magnetic moments; however, the reduced magnetization M/ M s is not observed to scale with H/ T; on the contrary, all curves are nearly exactly coincident when plotted against M s/ T. This result is phenomenologically interpreted in terms of an apparent average magnetic moment linearly growing with the ratio T/ M s.
