Abstract

Description

The results of electrical resistance (1.4 - 300 K), magnetization (2-300 K) and heat-capacity (2 - 50 K) measurements in Y$_2$PdGe$_3$, found to crystallize in a AlB$_2$-derived hexagonalstructure, are reported. The results establish that this compound is superconducting below 3 K. This obervation is interesting considering that this compound is the first superconductor among the ternary members derived from the hexagonal AlB$_2$ structure. With superconductivity being uncommon even among binary alloys derived from AlB$_2$ structure and with recent excitement on the observation of high temperature superconductivity in Mg$B_2$, this finding gains importance.
