Abstract
We have studied the relation between critical current density and pinning p otential in weak magnetic fields on highly oriented superconducting BSCCO f ilms, produced by sputtering. From the I-V characteristics we obtained the pinning potential U using the Aux creep theory. An increase of U upon incre asing J(c) was observed and analysed using the pinning of isolated vortex m odel.
