Title: Investigation on the Magnetocaloric Effect of the Pr{sub 7}Pd{sub 3} Compound

Abstract

Magnetic transitional behaviors and the magnetocaloric effect of the intermetallic compound Pr{sub 7}Pd{sub 3} have been studied. A second-order metamagnetic transition between ferromagnetic and paramagnetic states was observed with a Curie temperature (T{sub C}) of 14.9 K. The paramagnetic Curie temperature (𝜃{sub p}) and the effective magnetic moment (μ{sub eff}) were investigated and determined to be 5.1 K and 3.43 μ{sub B}/Pr, respectively. A reversible magnetocaloric effect was observed in this compound originated from the magnetic phase transition. For a magnetic field change of 0–5 T, the maximum magnetic entropy change − ΔS{sub M} reached 5.5 J kg{sup − 1} K{sup − 1}, and the corresponding value of refrigerant capacity was estimated to be about 65 J kg{sup − 1} with no thermal and field hysteresis loss.
