Using a mechanical method, we study the strength of Abrikosov fluxoid pinning in niobium single crystals as a function of the external magnetic field. It is shown that this dependence displays maxima near H/sub c/1 and H/sub c/2 and that the first is due to the existence of a barrier in the subsurface layer of the superconductor which hinders vortices in entering and leaving the specimen.
