Abstract
The c-axis dissipation in a magnetic field for oxygen-deficient YBa2Cu3O 7−δ single crystals is shown to agree with that of a series stack of Josephson tunnel junctions. The intrinsic Josephson coupling energy, thus obtained, indicates the possibility of increased c-axis coherence below Tc.
