Abstract: A novel magneto caloric material (MCM) is provided that can be used in, for example, a regenerator of a heat pump, appliance, air conditioning system, and other heating and/or cooling devices. The MCM is a type of Heusler alloy, has an L2 I crystal structural prototype, and can undergo a reversible phase transformation between a low temperature, low magnetization Martensite phase and a high temperature, high magnetization Austenite phase to exhibit an inverse magneto caloric effect upon application of a sufficient magnetic field. A process of annealing of the alloy is also provided that can be used to adjust the temperature at which this phase transformation occurs. The present invention includes the alloy as subjected to such annealing.
