Ferromagnetic shape memory alloys (FSMA) are capable of producing, magnetically induced strain of several percent at frequencies of the order of 1 kHz. The best performance exhibit alloys based on the Ni-Mn-Ga system. Off-stoichiometric single crystals of Ni2MnGa phase can produce up to 10% strain in the field below 1T.
