Abstract
The results of electrical resistance (1.4–300 K), magnetization (2–300 K) and heat-capacity (2–50 K) measurements in Nd2PdGe3 and Y2PdGe3, found to crystallize in an AlB2-derived hexagonal structure, are reported. The results establish that there is an onset of magnetic ordering (of a ferromagnetic type) for the Nd compound at a temperature close to 6 K and this temperature is considerably enhanced compared to the de Gennes scaled value. The Y compound is found to be superconducting below 3 K and this compound turns out to be a superconductor among the ternary members derived from the AlB2 structure. The identification of an AlB2-derived superconductor not containing B may contribute to the overall understanding of the physics of recently discovered high-temperature superconductor, MgB2.
