Abstract = {{We propose a mechanism that may account for the temperature-insensitive
   relaxation of the magnetic-shielding current  in epitaxial thin films of
   YBa2Cu3O7-delta.  We show that such relaxation is related to the shape
   of the current-voltage (J-E) characteristic of the superconductor in its
   critical state.  The weak temperature dependence of the relaxation
   implies a temperature-insensitive J-E characteristic that resembles that
   of conventional type-II superconductors when a spatial variation of
   critical current density (J(c)) is present.  We suggest such a
   distribution of J(c) as an explanation for the apparently large and
   temperature-insensitive relaxation observed in YBa2Cu3O7-delta.}},
