摘要：

The theoretical formalism behind the introduction of thermal activation into the micromagnetic approach is reviewed. The theory is introduced via an application to a single spin which shows a rapid increase of coercivity at short timescales of the order of nanoseconds. Interaction effects are shown to increase relaxation times. A model of thermally activated spin-waves is presented.
