Abstract
The magnetic properties of a Ba1-xKxBiOy film (x = 0.36) of thickness 18 mu m are investigated. It is shown that the field dependences J(c)(B) of crit ical currents at 5-20 K in fields above the peak-effect field H-p are corre ctly described in the collective pinning theory for a vortex lattice with a small bundle size.
