摘要	A large reversible negative magnetic-entropy change Delta S(M) has been observed in TbCoC(2), accompanied by a second-order phase transition at 28 K. The maximum value of -Delta S(M) is 15.3 J kg(-1) K(-1) at 30 K for a magnetic-field change from 0 to 5 T, with the refrigerant capacity of 354 J kg(-1). In particular, also the large -Delta S(M)(max) of 7.8 J kg(-1) K(-1), is obtained for a small field change from 0 to 2 T. The large reversible Delta S(M) and the high reversible refrigerant capacity in low magnetic field indicate that TbCoC(2) may be a promising candidate for magnetic refrigeration at low temperatures.
