Direct conversion of heat to electricity can be achieved using the multiferroic alloy Ni45Co5Mn40Sn10. This alloy undergoes a phase transformation from a nonmagnetic martensite to a strongly ferromagnetic austenite phase upon heating. When biased by a permanent magnet heating through the transformation causes an increase of the magnetization that induces a current in the coil.
