Abstract

We present a theoretical and experimental study of the peak effect in the surface pinning of vortices. It is associated with a sharp transition in the vortex slippage length which we relate to a crossover from a weakly disordered crystal to a surface glass state. Experiments are performed on ion-beam-etched Nb crystals. The slippage length is deduced from 1 kHz1 MHz linear AC penetration depth measurements.
