Abstract: A magnetic component including first and second regions, and a method of varying the magnetization values in different regions of the magnetic component are disclosed. The first and the second regions are characterized by a nitrogen content that is different from each other. At least one of the first region and the second region is partially-magnetic and has a nitrogen content in a range from about 0.1 weight % to about 0.4 weight % of that region. A concentration of carbon, if present, of both the first and second regions is less than about 0.05 weight % of the respective regions.

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 L21 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.
