Towards Dissipation-less Conduction in Oxide Topological Insulators
Abstract
In this program, we address the development of heterostructures with emergent topological behavior based on complex oxide materials. More specifically, we have incorporated epitaxial spinel ferrite oxide thin films into heterostructures in order to stabilize a magnetic topological insulator via magnetic proximity effect with a known topological insulator and topological spin textures via interfacial Dzyaloshinkii-Moriya interactions with a strongly spin-orbit coupled metal. Through this program, we have been able to enumerate the critical factors required for establishing a magnetic proximity effect between oxide and chalcogenide layers, and in turn, a magnetic topological insulator. In addition, we have also discovered signatures of topological spin textures in ferrite/Pt bilayers via Hall effect measurements.
