Multilevel computation of the demagnetization field in periodic domains applied to micromagnetism computations

Stéphane Labbé

Résumé

In many applications, for instance the simulation of the behaviour of ferromagnetic materials, the demagnetization field, approximation of the Maxwell contribution, has to be computed. One of the applications aimed by this paper is the simulation of ferromagnetic periodic layers. This type of layers could be, for example, structured poly-cristals or textured thin layers of dispersed ferromagnetic dots. In these two cases, in order to compute the evolution of a periodic magnetization, it becomes necessary to carefully take into account the demagnetization contribution. Indeed, the extension of non-periodic computations to periodic computations is not straightforward in the case of demagnetization field.
