摘要：
Bulk magnetic shape memory alloys like Ni-Mn-Ga single crystals reach high strains up to 10% in a moderate magnetic field. Epitaxial Ni-Mn-Ga films with a tailored microstructure are required for the integration into micro actuators. After shortly reviewing the recent progress towards active epitaxial films, this paper focuses on optimum growth conditions. The influence of deposition temperature on structure, ordering, transformation temperatures, magnetic hysteresis, composition and existence of magnetically induced reorientation (MIR) effect is analyzed in detail.
