Flux creep in the high T c oxide YBa2Cu3Oy superconductor in critical state has been investigated by observing the variation of magnetization with time. The experimental results show that in zero field cooled (ZFC) samples the magnetization decay is entirely logarithmic in time, and there is a magne
