Disorder-driven symmetry suppression by van der Waals planar defects in a magnetic topological insulator
Rikkie Joris, Heyi Xia, Ana Beatriz Pedro Fontes +17
Magnetic topological insulators offer a platform to control electronic topology through magnetic order, yet reliable routes to tune their properties remain limited. Here, we show t…
DC-operated Josephson junction arrays as a cryogenic on-chip microwave measurement platform
