Abstract

We have probed the Landau levels of nodal quasi-particles by tunneling along a nodal direction of (110) oriented YBa $_{2}$ Cu $_{3}$ O $_{7 - x}$ thin films with a magnetic field applied perpendicular to the $C u O_{2}$ planes, and parallel to the film's surface. In optimally doped films and at low temperature, finite energy nodal states are clearly observed in films thinner than the London penetration depth. Above a well defined temperature the order parameter reverts to a pure \emph{d}-wave symmetry.
