Magnetic Properties and Magnetocaloric Effect of Binary Compound NdPd

The crystal structure, magnetic and magnetocaloric properties of the binary NdPd compound were investigated by X-ray diffraction and the physical property measurement system in detail. The NdPd compound with a CrB structure exhibits a second-order magnetic phase transition from ferromagnetic to paramagnetic states at the Curie temperature TC = 15.5 K. For a magnetic field change of 0–5 T, the peak value of magnetic entropy change (− ΔSM) is evaluated to be 12.2 J/kg K, and the corresponding refrigerant capacity (RC) reaches its maximal value of 94 J/kg. The relatively small thermal hysteresis and magnetic hysteresis with the considerable magnetocaloric effect indicate that NdPd is an anticipated material for the low-temperature magnetic refrigeration.
