Magnetic phase transitions and large magnetocaloric effects in equiatomic binary DyZn compound

The magnetic properties and magnetocaloric effect (MCE) in dysprosium zinc binary DyZn compound were studied. The compound reveals a paramagnetic-to-ferromagnetic transition together with a spin reorientation phenomenon at Curie temperatures of TC ∼135 and TSR ∼50 K, respectively. A large reversible MCE was observed in DyZn around TC. For the magnetic field change of 0-7 T, the values of maximum magnetic entropy change (-ΔSMmax), relative cooling power (RCP), and refrigerant capacity (RC) were 12.2 J/kg K, 895 J/kg, and 672 J/kg, respectively.
