Abstract:We study the position-dependence of vortex motion around asymmetric mesoscopic superconducting ring for the external current flowing from inner boundaries to outer boundaries based on time-dependent Ginzburg-Landau theory. The inner hole position can have a great impact on not only the vortex configuration but also the current-voltage (I-V) characteristics. Different from the vortex rotation in the symmetric structure, we demonstrate that vortices enter/exit from outer boundaries periodically and the formation… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
