The animation shows a thermally activated magnetization reversal process of a small cubic particle, which has been discretized with eight magnetization vectors. A finite difference and finite element micromagnetics code, which solves the stochastic differential equation in the sense of Stratonovich, has been developed to perform temperature dependent simulations. Detailed information on the numerical micromagnetic simulation of thermally activated switching can be found in my diploma thesis.
