Abstract
In this article we present a phenomenological model which simulates very well the mag- netic relaxation behavior experimentally observed in small magnetic grains and single domain particles. In this model, the occurrence of quantum tunneling of magnetization below a certain temperature is taken into account. Experimental results for different materials are presented to illustrate the most important behavior deduced from our model.This publication has 16 references indexed in Scilit:
