Room temperature Epitaxial Stabilization of a Tetragonal Phase in ARuO3 (A=Ca,Sr) Thin Films

Arturas Vailionis, Wolter Siemons, Gertjan Koster

We demonstrate that SrRuO3 and CaRuO3 thin films undergo a room temperature structural phase transition driven by the substrate imposed epitaxial biaxial strain. As tensile strain…
