The skyrmion-substrate interaction is an important issue to consider when studying particle-like skyrmions in nanostructures, which may strongly affect the skyrmion dynamics and lead complex dynamic phenomena. Here, we report current-driven behaviors of interacting with funnel obstacle a ferromagnetic layer. We computationally demonstrate that enhanced perpendicular magnetic anisotropy can be u...

The hypothetical axion and axion-like particles, feebly coupled with photon, have not yet been found in any experiment. With the improvement of laser technique, much stronger but shorter quasi-static electric magnetic fields can be created laboratory using laser-plasma interaction, compared to large magnets, help search axion. In this article, we discuss feasibility ALPs exploration planarly or...
