Abstract: The magnetic properties and magnetocaloric effect (MCE) of binary intermetallic compound Er 3 Pd 2 were studied. It exhibits a paramagnetic (PM) to antiferromagnetic (AFM) transition at Néel temperature (T N ) = 10 K. A large reversible MCE was observed which is related to a second order magnetic transition from PM to AFM state. The values of maximum magnetic entropy change ( - Δ S M max ) and adiabatic temperature change ( Δ T ad max ) reach 8.9 J/kg-K and 2.9 K respectively for the field change of 50 kOe with no obvious hysteresis loss. The effective magnetic moment was determined to be 10.16 µ B /Er 3+ , which is notably higher than that of free ion value of Er 3+ (9.59 µ B ), suggests that Pd ions also have considerable amount of magnetic moments in this compound.
