Jun 22 2011 Abstract. We demonstrate a new method for the direct conversion of heat to electricity using the recently discovered multiferroic alloy Ni 45 Co 5 Mn 40 Sn 10 1. This alloy undergoes a low hysteresis reversible martensitic phase transformation from a nonmagnetic martensite phase to a strongly ferromagnetic austenite phase upon heating.
