Abstract
Low field low frequency a.c susceptibility measurements show that the response is strongly non linear, the shielding current growing subline arly with the increase of the applied field, and irreversible down to 50 mu G. A new model of diamagnetic response is proposed, based on the idea of a fractal organization of the free energy landscape in the gr anular network.
