In this paper AgNiFe alloy films were examined both before and after annealing. Characterization of the samples and examination of interaction effects was carried out by measuring the temperature decay of remanence, initial susceptibility, and magnetoresistance. The temperature decay of remanence reveals that annealing widens the distribution of energy barriers, which is indicative of grain growth. The behavior of the initial susceptibility as a function of temperature is analogous to that found in spin glasses. From these measurements, it is believed that interaction effects in these systems are small.
