Magnetic Insulator Stabilized $\alpha$-Bismuthene with a Large Room-Temperature Gap Consistent with a Quantum Spin Hall State

Interfacing two-dimensional bismuth with a magnetic substrate has been proposed as a promising route for exploring magnetically tunable topological states. Here, we report the experimental realization of epitaxial bismuthene-magnetic insulator heterostructure by growing ultrathin Bi films on ferromagnetic EuO(111). T...
