Single crystals of magnetic shape-memory materials display a large spontaneous deformation in response to an applied magnetic field. In polycrystalline material samples the effect is frequently inhibited by incompatibilities at grain boundaries. This motivates technological interest in textured polycrystals and composites of single-crystal magnetic shape-memory particles embedded in a soft polymer matrix. We use a continuum model based on elasticity and micromagnetism to study the induced macroscopic material behavior in dependence of such mesoscopic structures via numerical simulation in two dimensions.
