| Popis: | The temperature dependence of the critical current of NbN thin-film bridges was experimentally studied. At low temperatures we observed significant enhancement (up to two times at 4 K) of the critical current density over de-pinning value in the sub-micrometer wide bridges. This enhancement can be described by an increase of the edge barrier for penetration of magnetic vortices into narrow superconducting strips. |
