Abstract

We investigated the Ericsson type magnetic refrigerators in the range below 77 K. This is the first report of experimental results of the refrigeration character, especially the magnetocaloric character of RAl//2, where R is a rare earth atom. The specific heat and magnetization were measured precisely as a function of temperature and magnetic field. From analyses of these results the total entropies S and the magnetic entropy changes DELTA S//J of the RAl//2 series were determined. It is made clear that a large enough value of DELTA S//J to make refrigeration can be induced by the external magnetic field near T//c, and also that the temperature corresponding to the maximum value of DELTA S//J is adjustable by making a solid solution between the compounds in the RAl//2 series. It is therefore concluded that the RAl//2 series is a promising candidate for refrigerant at above 20 K.
