Electronic reconstruction at the interface of SrIrO<sub>3</sub> and SrRuO<sub>3</sub>

ORAL

Abstract

The interface between SrIrO3 and SrRuO3 has been the focus of much attention due to reports of emergent phenomena including the topological Hall effect and magnetic skyrmions. However, due to the presence of electron correlations, strong spin orbit interactions, and ferromagnetism, the electronic structure of the interface is challenging to predict and understand. Here we employ a combination of oxide molecular-beam epitaxy, in situ angle-resolved photoemission spectroscopy, scanning transmission electron microscopy, and density functional theory to investigate heterostructures of SrIrO3 / SrRuO3. We perform a systematic investigation of the electronic structure of (SrIrO3)n/ (SrRuO3)20, spanning n = 1 to 10 to investigate the electronic reconstruction as a function of distance from the interface.
