Dipolar model of surface magnetostriction for thin polycrystalline films

Abstract A simple model of the dipolar origin of magnetostriction for thin polycrystalline BCC films has been proposed, which is based on the angular averaging of the magnetoelastic energy tensor. The cases of polycrystalline layers with [1 0 0] and [1 1 0] texture, as well as entirely polycrystalline films, have been considered. The surface effects in dipolar magnetostriction have been estimated for FeCo systems.
