Abstract
We present the results and interpretations for two types of diamagneti c peaks observed in magnetization versus temperature curves, taken for field cooled on warming (FCW) experiments in YBa2Cu3O7-delta samples. The high field data (2.0 < H < 4.5 T), for a high quality twinned cry stal, presents a universal behavior described by the collective flux c reep theory.
