We report a small roughly logarithmic increase with frequency of the apparent transition temperature in ac susceptibility experiments on a Y-Ba-Cu-O superconducting crystal. Magnetic field enhances the effect. A flux creep model predicts the correct order of magnitude and implies that the transitions previously used to determine the upper-critical field Hc2 actually represent an "irreversibility" line. © 1988 The American Physical Society.
