Electronic and magnetic properties of epitaxial SrRhO3 films

TL;DR

This study successfully synthesizes high-quality epitaxial SrRhO3 films and explores their unique structural, electronic, and magnetic properties, revealing significant differences from bulk behavior due to octahedral rotations.

Contribution

First demonstration of epitaxial SrRhO3 films with detailed analysis of their properties and the impact of octahedral rotations.

Findings

SrRhO3 films are structurally stabilized and epitaxial.

Electronic and magnetic properties differ from bulk, showing non-paramagnetic behavior.

Properties are strongly influenced by RhO6 octahedral rotations.

Abstract

Strong interplay of fundamental order parameters in complex oxides are known to give rise to exotic physical phenomena. The 4d transition metal oxide SrRhO3 has generated much interest, but advances have been hindered by difficulties in preparing single crystalline phases. Here, we have epitaxially stabilized high quality single crystalline SrRhO3 films and investigated their structural, electronic, and magnetic properties. We determine that their properties significantly differ from the paramagnetic metallic ground state that governs bulk samples and are strongly related to rotations of the RhO6 octahedra.
