Effects of artificial square nanorods array to square bulk superconducting plate

Abstract

It is known that the superconducting properties are improved by adding nanorods to a superconductor. As increasing nanorods into superconductor, the pinning force becomes stronger. Using the molecular dynamics method, we investigate vortex motions in a superconductor with a nanorod array. We obtain trajectories of vortices and standard deviation of vortex positions. We find peculiar temperature dependence of vortex motion.
