Pinning of plane vortices in three-dimensional Josephson medium and applicability of the Bean model

The system for plane vortices formed near the sample boundaries by the external magnetic field monotonous growth, is calculated with an account of pinning, caused by the medium porosity. The distance between the vortices remains approximately constant, which that the magnetic film does not depend on the coordinate in the area, wherein the vortices penetrate. These facts contradict the generally accepted Bean model
