The observation of two kinds of oscillations provide clear evidence of coexistence of the nontrivial topological Dirac state and trivial electron state on the surface of topological insulator nanowires.
Skyrmions, a topological stable nano-sized magnetic vortex, has been proved to exist in chiral magnets including specific metallic alloys with B20 structure such as MnSi, FeGe, FexCo1-xSi, two-dimensional Fe/Ir(111) film, and even insulating oxide Cu2OSeO3. In metallic helimagnet this topological...
