Abstract

Lattice constants, electrical resistivity, heat capacity, AC and DC magnetic susceptibility and 151Eu Mossbauer effect studies on a new intermetallic compound, Eu2PdSi3, found to crystallize in an AlB2-derived hexagonal crystal structure, are reported. The results establish that the Eu ions are in the divalent state down to low temperatures, undergoing two magnetic transitions, one at 40 K and the other at 10 K, pertaining to two different Eu sites. Interestingly, the minority Eu ions at the 2(b) sites order at a relatively high temperature (40 K) and this magnetic interaction is inferred to be ferromagnetic and quasi one-dimensional along the c-axis. The magnetic structure below 5 K following magnetic ordering (at 10 K) of the majority ions at 6(h) sites appears to be quite complex. In short, the crystallographic and (hence) the overall magnetic behaviors of this compound present an interesting situation.
