Abstract
It is demonstrated that the irreversible magnetic flux penetration in a type II Nb superconducting strip, slightly above Hc1, happens by the discrete entry of flux bundles each of them containing several hundre ds of quanta. This is in contrast with the reversible regime in which the magnetic penetration is continuous. This non linear regime is stud ied as a function of the strip dimensions thus establishing a case of geometrical metastability in type II strips.
