Abstract
The magneto-optical technique was used to study the edge barrier in ty pe I superconducting strips. We measured the flux-free zones in the sa mple edges and its dependence on the field magnitude and temperature. Standard I-V measurements allowed us to saury the critical current ori ginated bp the edge barrier in these pinning-free samples. Our results show the predominant role of the geometrical edge barrier.
