We study the homogenization process of
ferromagnetic multilayers in the presence of surface energies:
super-exchange, also called interlayer exchange coupling,
and surface anisotropy. The two main difficulties are the non-linearity
of the Landau-Lifshitz equation and the absence of a good sequence
of extension operators for the multilayer geometry.
First, we consider the case when surface anisotropy
is the dominant term, then the case when the magnitude of the super-exchange
interaction is...
A homogenization problem related to the micromagnetic energy functional is studied. In particular, the existence of the integral representation for the homogenized limit of a family of energiesof a large ferromagnetic body is obtained.
