Abstract

Time resolved magneto-optical images show hysteresis associated with the transition at the so-called ``second magnetization peak'' at Bsp in single-crystalline Bi2Sr2CaCu2O8+d. By rapid quenching of the high-field phase, it can be made to persist metastably in the sample down to fields that are nearly half Bsp.
