A preparation method of a complex type RAl2 magnetic system (where R denotes rare earth ions) for Ericsson type magnetic refrigerator is investigated. Previously, the authors reported on the model complex magnetic refrigerant with layer structure and concluded that this complex magnetic refrigerant shows a temperature independent magnetic entropy change ΔSM in particular temperature range, which is suitable for the Ericsson cycle, satisfying the Carnot principle.
In this paper, the preparation of a complex type RAl2 magnetic mixture by a shock compression method, which is a high density mixture of its components in grain size scale, is described and its thermal and magnetic properties are discussed in respect to application to the Ericsson type magnetic refrigerant.
