摘要:

We have, for the first time, made quasi‐particle tunneling measurements on a YBa2Cu3O7−x(001)/Y2O3(001)/YBa2Cu3O7−x(001)junction, which was epitaxially grown on a MgO(100) substrate in anin‐situprocess. Both layers of YBa2Cu3O7−xshowed the same superconducting transition ofTc end=86 K with &Dgr;T(R=10–90%)=1.5 K. Quasi‐particle tunneling in the direction perpendicular to the Cu‐O planes was measured. A gap parameter &Dgr;(4.5 K) of 9.0±0.2 meV and a value of 2&Dgr;/kTcof 3.5+0.4−0.6were obtained.
