Angle and electric field dependent electrical transport in magnetic topological insulators

ORAL

Abstract

Magnetic topological matter has received significant attention as a potential building block in future spintronic and quantum computing technologies. Notably, through careful simultaneous tuning of the magnetic exchange gap and electronic band structure, these systems have been shown to exhibit novel electronic states, including the quantum anomalous Hall insulator phase. In this talk we present the electrical transport properties of a high quality magnetic topological insulator subject to magnetization rotation and electric field tuning; discussing the contributions of bulk, surface, and chiral edge states to the observed transport signatures.
