Large reversible magnetocaloric effect in Tb3Co compound

A large reversible magnetocaloric effect has been observed in Tb3Co compound. Under a magnetic field change of 5T, the maximum value of magnetic entropy change ΔSM is −18Jkg−1K−1 at 84K and the relative cooling power is 738Jkg−1 with no hysteresis loss. In particular, the large reversible ΔSMmax, −8.5Jkg−1K−1, is achieved for a low magnetic field change of 2T. The magnetic anisotropy and the texture of the material greatly affect ΔSM. The large reversible magnetocaloric effect (both the large ΔSM and the high relative cooling power) indicates that Tb3Co could be a promising candidate for magnetic refrigeration.
