Abstract
The results of electrical resistance, magnetization and heat-capacity measurements in Y2PdGe3, crystallizing in an AlB2-derived hexagonal structure, establish that this compound is superconducting below 3 K. This is the first superconductor among the ternary members derived from the hexagonal AlB2 structure. The band structure calculations reveal that the Fermi level (EF) is dominated by Y 4d density of states, and therefore these states are presumably responsible for superconductivity; this situation is somewhat different from that in recently discovered high-temperature superconductor MgB2 (isostructural to Y2PdGe3), in which superconductivity is attributed to B.
