摘要	The intermetallic compound Tb(2)In exhibits two magnetic phase transitions: a paramagnetic-ferromagnetic transition at T(C) of 165 K and a ferromagnetic-antiferromagnetic one at 45 K. A large reversible magnetocaloric effect is observed in Tb2In. For a magnetic field change of 5 T, the maximum magnetic entropy change -Delta S(M) is 6.6 J/kg K at T(C). Meanwhile, the full width at half maximum (delta T(FWHM)) of the -Delta S(M) - T curve has a very high value of 100 K and relative cooling power (RCP) is as high as 660 J/kg with no hysteresis loss. In particular, the large reversible -Delta S(M) (3.5 J/kg K), delta T(FWHM) (57 K) and RCP (200J/kg) are achieved for a low field change of 2 T. The large reversible magnetic-entropy changes, together with high delta T(FWHM) and RCP values indicate that Tb(2)In is a suitable candidate material for magnetic refrigeration.
