Abstract
An approximate closed form expression for the elementary pinning force of a grain boundary is used to evaluate the bulk pinning force, in the isolated vortex regime, of a type-II superconductor with grain sizes smaller than the flux line spacing. A comparison is made with experimental results on NbN films.Keywords
