In this research,ESR method is especially employed for its high sensitive to superconductivity. With the careful analysis of the ESR spectra between 35K and 44K,the new 44K-superconductor phase was certified,and Hc1 was obtained.

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...
