Abstract
A large reversible magnetocaloric effect over a wide temperature region has been observed in the compound Dy2In. For a magnetic-field change of 5 T, the maximum magnetic-entropy change -ΔSM is 9.2 J kg -1 K-1 at 126 K. The full width at half maximum (δTFWHM) of the -ΔSM versus T curve has a high value of 80 K and the relative cooling power (RCP) is as high as 736 J kg -1 with no hysteresis losses. In particular, a large reversible -ΔSM (4.6 J kg-1 K-1), large δTFWHM (50 K) and large RCP (230 J kg-1) are also achieved for a low field change of 2 T. Therefore, Dy2In may be an interesting material for low-temperature magnetic refrigeration.
