Original Paper


Magnetic transitional behaviors and the magnetocaloric effect of the intermetallic compound Pr7Pd3 have been studied. A second-order metamagnetic transition between ferromagnetic and paramagnetic states was observed with a Curie temperature (T C) of 14.9 K. The paramagnetic Curie temperature (𝜃 p) and the effective magnetic moment (μ eff) were investigated and determined to be 5.1 K and 3.43 μ 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 M reached 5.5 J kg− 1 K− 1, and the corresponding value of refrigerant capacity was estimated to be about 65 J kg− 1 with no thermal and field hysteresis loss.
