Geometric Space-Time Integration of Ferromagnetic Materials
The Landau-Lifshitz equation (LLE) governing the flow of magnetic spin in a ferromagnetic material is a PDE with a noncanonical Hamiltonian structure. In this paper we derive a number of new formulations of the LLE as a partial differential equation on a multisymplectic structure. Using this form we show that the standard central spatial discretization of the LLE gives a semi-discrete multisymp...
متن کاملHomogenization of ferromagnetic materials
In these notes we describe the homogenzation theory for ferromagnetic materials. A new phenomenon arises, in particular to take into account the geometric constraint that the magnetization is locally saturated.
متن کاملFrustration in ferromagnetic materials
We examine the theory of micromagnetics developed by W. F. Brown. We show that in the case often considered, with exchange energy omitted, the minimum of the free energy is not attained for uniaxial materials but is attained for cubic materials. A study of the minimizing sequences reveals that these accurately model many features of observed domain structure. Finally, we reexamine the so-called...
متن کاملNumerical Simulations of Ferromagnetic Materials
In this article, we give a glimpse on our last works in simulation of ferromagnetism phenomena. The main problems encountered in this type of computation are the demagnetization field and the microwave susceptibility computations. Difficulties for the demagnetization field come principally form the fact that the operator is nonlocal and the discretized operator gives a full matrix, we will focu...
متن کاملHomogenization of Composite Ferromagnetic Materials
The objective of this paper is to perform, by means of Γ -convergence and two-scale convergence, a rigorous derivation of the homogenized GIBBS-LANDAU free energy functional associated to a composite periodic ferromagneticmaterial, i.e. a ferromagneticmaterial in which the heterogeneities are periodically distributed inside the media. We thus describe the Γ -limit of the GIBBS-LANDAU free energ...
