The model of a surface barrier was found to explain well the observed behaviour in quasistatic magnetization experiments on high T c superconductors. We study this phenomenon in dynamic conditions in an AC magnetic field with frequencies ranging from 3 Hz up to 115 kHz. The experimental data recorde
