| dc.description | The existence of Josephson tunneling has been demonstrated between YBa$_2$Cu$_3$O$_{7-δ}$ and Pb with the current flowing along the c-axis of YBa$_2$Cu$_3$O$_{7-δ}$. This is presumed to come from an s-wave component of the superconductivity in YBa$_2$Cu$_3$O$_{7-δ}$, perhaps induced by the orthorhombic distortion. This hypothesis by itself appears to be in contradiction with experiments on twinned samples whose tunneling current does not follow random statistics. We present a theory which depends on a competition between the intertwin d-wave coupling and a relatively enhanced s-wave component on the surface. This theory appears to explain, at least qualitatively, all observations made to date. | |
