Field-dependent critical current in type-II superconducting strips: Combined effect of bulk pinning and geometrical edge barrier
Recent theoretical and experimental research on low-bulk-pinning superconducting strips has revealed striking domelike magnetic-field distributions due to geometrical edge barriers. The observed magnetic-flux profiles differ strongly from those in strips in which bulk pinning is dominant. In this paper we theoretically describe the current and field distributions of a superconducting …
