Abstract: A regenerator having a thermal diffusivity matrix is presented. The thermal diffusivity matrix includes magneto-caloric material having multiple miniature protrusions intimately packed to form a gap between the protrusions. A fluid path is provided within the gap to facilitate flow of a heat exchange fluid and further provide efficient thermal exchange between the heat exchange fluid and magneto-caloric material. A first layer is disposed on each of the miniature protrusion to physically isolate the heat exchange fluid and magneto-caloric material, wherein the first layer further includes a soft magnetic material configured to simultaneously enhance a permeability and a thermal efficiency of the thermal diffusivity matrix.
