摘要： As magnetically working substances capable of producing magnetically working abilities such as magnetic refrigeration or cooling in a wide range of temperatures with high efficiency, this invention utilizes amorphous alloys possessing a large magnetic moment and the spin glass property. Concrete examples of the amorphous alloys which meet the requirement are amorphous alloys containing rare earth metals, the same amorphous alloys absorbed hydrogen therein, and Fe-based amorphous alloys containing additional elements for formation of the amorphous phase. One element or the combination of two or more elements selected from the group just mentioned can be used, with the composition of alloys so adjusted for the desired magnetic transition points to be distributed or for the different magnetic transition points to be continuously distributed in a range of high to low temperatures. The magnetically working substances so produced are enabled to create magnetically working abilities by exposing to an external weak or strong magnetic field and subsequently adiabatical demagnetizing. It finds utilities in applications to very big plants such as MHD power generation, nuclear fusion, and energy storage and to various devices such as linear motors, electronic computers and their peripheral appliances.
