Abstract :

From heat capacity measurements performed in the 5-350 K temperature range at 0- and 5-Tesla applied magnetic field on the intermetallic compounds Gd₇Pd₃ and Gd₇Pd₂Ni, and on the eutectic between Gd and Gd₇Pd₃ with composition Gd₇₆Pd₂₄, the main magnetocaloric properties of the alloys were obtained, namely the isothermal entropy change ΔS_M, the adiabatic temperature rise ΔT_ad and the refrigerant capacity Q.
