چکیده انگلیسی
The magnetic properties, magnetocaloric effect (MCE) and universal behaviour of ternary Cadmium compounds Gd2Cu2Cd and Er2Cu2Cd have been investigated systematically. A second order magnetic phase transition from a paramagnetic to ferromagnetic state is observed for Gd2Cu2Cd and Er2Cu2Cd at their own Curie temperatures of TC â¼120 and 36 K, respectively. A large reversible MCE occurs near its own TC for both compounds. The maximum values of magnetic entropy change (âÎSMmax) are 10.1 and 19.1 J/kg K under a magnetic field change of 0-7 T with no obviously hysteresis loss for Gd2Cu2Cd and Er2Cu2Cd, respectively. The corresponding values of refrigerant capacity (RC) and relative cooling power (RCP) are evaluated to be 386 and 373 J/kg, and to be 525 and 489 J/kg, respectively. The rescaled magnetic entropy change curves collapse onto a single curve for various magnetic fields, further confirming the Gd2Cu2Cd and Er2Cu2Cd compounds with the second order phase transition.
