title: Large magnetocaloric effect and near-zero thermal hysteresis in the rare earth intermetallic Tb1-xDyxCo2compounds.
abstract: We report the magnetocaloric effect in a Tb1-xDyxCo2compound which exhibits a wide working temperature window around the Curie temperature (TC) and delivers a large refrigerant capacity (RC) with near-zero thermal hysteresis. Specifically, the wide full width at half maxima ([Formula: see text]) can reach up to 62 K and the RC value changes from 216.5 to 274.3 J Kg-1when the external magnetic field increases to 5 T. Such magnetocaloric effects are attributed to a magnetic and structural transition from a paramagnetic and cubic phase to a ferromagnetic (MSalong [1 1 1] direction) and rhombohedral phase or ferromagnetic (MSalong [0 0 1] direction) and tetragonal phase.
