Abstract
The subharmonic gap structures corresponding to large, 2 Delta(1) = 48 meV, and small, 2 Delta(2) = 10.3 meV, components of the energy gap w ere observed in the first derivatives of the current-voltage character istics of YBa2Cu3O7-x epitaxial thin film microbridges. The appearance of the subharmonic gap structures is attributed to Andreev reflection .
