Abstract
The magnetic properties and magnetocaloric effect (MCE) in the ternary intermetallic compound EuAuZn have been studied via magnetization and heat capacity measurements. The compound orders ferromagnetically below T C ~ 52 K with a spin reorientation transition at T SR ~ 19 K. A large reversible MCE has been observed in EuAuZn accompanied by a second-order magnetic phase transition from a paramagnetic to a ferromagnetic state. Under a field change of 5 T, the maximum values of magnetic entropy change (-ΔS M max ) and adiabatic temperature change (ΔT ad max ) are 9.1 J/kg·K and 3.8 K, respectively, the corresponding relative cooling power is 318 J/kg.
