  • A large reversible magnetocaloric effect has been observed in Tb(3)Co compound. Under a magnetic field change of 5 T, the maximum value of magnetic entropy change Delta S(M) is -18 J kg(-1) K(-1) at 84 K and the relative cooling power is 738 J kg(-1) with no hysteresis loss. In particular, the large reversible Delta S(M)(max), -8.5 J kg(-1) K(-1), is achieved for a low magnetic field change of 2 T. The magnetic anisotropy and the texture of the material greatly affect Delta S(M). The large… CONTINUE READING
