In this paper we study the asymptotic behavior of the solutions of time dependent micromagnetism problem in a structure consisting of two joined thin wires. We assume that the volumes of the two parts composing the multi-structure vanish with same rate. We obtain two 1D limit problems coupled by a junction condition on the magnetization. The limit problem remains non-convex, but now it becomes completely local.

Abstract
In this paper we study the asymptotic behavior of the solutions of time dependent micromagnetism problem in a structure consisting of two joined thin wires. We assume that the volumes of the two parts composing the multi-structure vanish with same rate. We obtain two 1D limit problems coupled by a junction condition on the magnetization. The limit problem remains non-convex, but now it becomes completely local.File in questo prodotto:
