Abstract

The numerical computation of the minimum energy for a ferromagnetic material with a fine domain structure modeled by the theory of micromagnetics is difficult because the bulk energy has many local minima and because the optical magnetization can have many domains. We show that an efficient implementation of the simulated annealing algorithm can be used to compute the magnetization which has the minimum energy.
