Researchers discovered that a hidden ferromagnetic insulating (FMI) state emerged in Sr2Fe1+xRe1-xO6 films when the material’s local ionic order was disturbed by a small modification in cation ratio.1 This work provides a promising new route to developing
This work directly measured the intrinsic surface conductance of topological insulators by using a four-probe scanning tunneling microscope (4-Probe STM) to tune the crossover of bulk-to-surface conductance. A scattering-free spin transport
