This paper presents a simple method to examine whether a ferromagnetic shape memory alloy can be used as an actuator by controlling the transformation temperature by magnetic field. Both Fe-Pd and NiAlCo alloys are studied. The analysis results show the recently discovered alloy of NiAlCo cannot be used. Although an Fe-Pd alloy can be used, in principle, for magnetic field actuation, the work extracted by magnetic actuation is small. Published by Elsevier Science Ltd on behalf of Acta Materialia Inc.
