ABSTRACT:
The invention provides a method of making a magnetic regenerator for an active magnetic refrigerator, the method comprising: forming a magnetic regenerator from a slurry or a paste containing a magnetocaloric material the magnetic regenerator being formed to have plural paths therethrough for the flow of a heat transfer fluid; and varying the composition of the magnetocaloric material so that the magnetic transition temperature of the magnetic regenerator varies along the paths.
