Abstract

Flux penetration into superconducting tin strips, induced by incrementation of a perpendicular magnetic field, is observed by the detection in real time of flux variations while the field is increased up to H_c. Three different flux penetration regimes are observed, well separated by two limiting fields. The limits of the different flux penetration regimes are determined by the sample geometry. These results allow a reinterpretation of previous magneto-optic observations, providing a simple picture associating the energy barrier against flux penetration into superconducting strips with the presence of entirely diamagnetic bands at the strip borders.
