Ferromagnetic shape memory alloys (FSMAs) experienced a widespread research boom as they exhibit a unique combination of high energy densities, thermoelastic and ferromagnetic properties. Of particular interest have been the Heusler ferromagnetic shape memory alloys Ni-Mn-Ga, which in single crystalline state show the giant magnetostrain effect. Currently, thin film technology is being developed intensively in order to pave the way for applications in microsystems and nanotechnology. For engineering of novel devices, test systems need to be developed and investigated with respect to their spatially and time-resolved physical behaviour in order to clarify the underlying fully coupled thermo-magneto-mechanical material properties.
