Abstract
⺠TbPdAl compound undergoes a field-induced metamagnetic transition from antiferromagnetic (AFM) to ferromagnetic (FM) state below TN, which gives rise to a large magnetocaloric effect (MCE). ⺠Sign change of MCE from negative to positive with magnetic field and temperature increase is observed below TN near the critical field at which the metamagnetic transition occurs. ⺠Maximal value of magnetic entropy change for TbPdAl is found to beâ11.4 J/kg K with a refrigerant capacity of 350 J/kg around TN for a field change of 0-5 T. ⺠Good magnetocaloric property of TbPdAl results from the high saturation magnetization caused by the field-induced AFM-FM transition.
