Abstract
We have studied the magnetoresistance (MR) and magnetization of thin discon tinuous films of Ni quench-condensed on an insulating substrate. These film s show a crossover from superparamagnetic to ferromagnetic behavior as incr easing amounts of Ni are added to the film and the film becomes more contin uous. We describe the characteristics of this crossover and compare the MR and the magnetization measurements. (C) 2000 Elsevier Science Ltd. All righ ts reserved.
