The nature of dissipation in high temperature superconductors in the presence of an applied magnetic field is an area of considerable controversy. Measurements of V(I) in films as well as crystals of YBa2Cu3O7 delta have been cited as evidence for a vortex-glass transition. Consequently, conventional flux-creep models which were proposed for these materials have been called into question. The authors have performed (T) and V(I) measurements on YBa2Cu3O7-delta crystals in order to help clarify this matter. Crystals of YBa2Cu3O7-delta were grown using a self-decanting flux method. After removal from the flux, the crystal used in this study was annealed for about 10 days at 450 C in flowing O2.
