![Illustration of spin and orbital structures Illustration of spin and orbital structures of the Sr2FeReO6 double perovskite composed of localized 3d orbitals (red) and spin-orbit coupled 5d orbitals (blue).](/sites/default/files/styles/list_page_thumbnail/public/Image%20for%20Lee%20highlight%2012-03-18.jpg?itok=jJpOWi3U)
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

This work successfully demonstrated size and geometry customizable carbon microelectrode sensors using templates produced with the CNMS Nanoscribe.
![Next-generation fiber-reinforced composites may monitor their own structural health, detect damage, and issue early warnings. When enough electrically conductive fiber is embedded in a polymer matrix, the bulk composite becomes electrically conductive.
