Magnetic, magnetocaloric and magnetoresistance properties of the intermetallic compound Nd7Pd3 have been investigated. It exhibits a first-order magnetic phase transition at its ferromagnetic ordering temperature (TC = 34K). Just above the TC, the magnetization isotherms exhibit a metamagnetic transition from the paramagnetic to a ferromagnetic state. In the immediate vicinity of TC, a field change of only 10kOe leads to the giant magnetocaloric effect of 13 J mol -1 K-1. For a field change of 50kOe a large magnetoresistance of ∼21% is observed near TC. First-principles electronic structure calculations indicate that the first-order phase transition in Nd7Pd3 may originate from the peculiar nature of the density of states near the Fermi level.
