Phase-Transition Temperatures of Strained Single-Crystal SrRuO3 Thin Films

Abstract

The temperature dependence of in-plane and out-of-plane lattice parameters of a compressively strained SrRuO3 thin film grown on a SrTiO3 substrate is reported. The structural transition temperature of the SrRuO3 thin film shifts by more than 200 degrees C toward the lower-temperature region due to compressive strain (see graph).
