N2 - We have investigated the coupled structural and electronic phase transition in the rare-earth ternary silicide Lu2 Ir3 Si5 by means of electrical resistivity (ρ), Seebeck coefficient (S), as well as thermal conductivity (κ) measurements. Near the phase transition, pronounced anomalies in these transport properties with a significantly large hysteresis of about 40 K were noticed. By comparing the transition characteristics with the earlier reported charge-density-wave (CDW) systems R5 Ir4 Si10 (R=rare-earth elements), our present investigation infers the possibility for the CDW transition accompanying a structural transition in this compound. In addition, possible mechanisms for the observed thermal hysteresis have also been proposed.
