Abstract

The intermetallic compound Tb₂In 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 - Δ S_M is 6.6 J/kg K at T_C. Meanwhile, the full width at half maximum (δ T_FWHM) of the - Δ 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 - Δ S_M (3.5 J/kg K), δ T_FWHM (57 K) and RCP (200 J/kg) are achieved for a low field change of 2 T. The large reversible magnetic-entropy changes, together with high δ T_FWHM and RCP values indicate that Tb₂In is a suitable candidate material for magnetic refrigeration. Crown
