Various technological means were tested in order to elaborate the conditions for obtaining magnetic field-induced strain (MFIS) by twin boundary motion in polycrystalline Ni–Mn–Ga. The influence of those technological means on microstructure and their relation to magneto mechanical behavior are presented. The possibility to obtain stable MFIS of more than 1% over more than 1 million cycles was demonstrated.
