Abstract

We have studied the magnetoresistance (MR) and magnetization of thin discontinuous films of Ni quench-condensed on an insulating substrate. These films show a crossover from superparamagnetic to ferromagnetic behavior as increasing amounts of Ni are added to the film and the film becomes more continuous. We describe the characteristics of this crossover and compare the MR and the magnetization measurements.
