Abstract

A giant reversible MCE and large RC in EuTiO₃ compound were observed. Under the magnetic field changes of 5 T, the maximum value of -ΔS_M is evaluated to be 40.4 J/kg K, and the value of RC is 328 J/kg in EuTiO₃ compound. Especially, for the magnetic field changes of 1 and 2 T, the large values of -ΔS_M are 11 and 22.3 J/Kg K without magnetic and thermal hysteresis are also obtained, respectively. The giant MCE is attributed to field-induced AFM-FM transition and FM-PM transition. Therefore, the giant reversible MCE and large RC make the EuTiO₃ compounds could be considered as a good candidate material for low-temperature and low-field magnetic refrigerant.
