Abstract
We report planar tunneling measurements on thin films of YBa2Cu3O7−x at various doping levels under magnetic fields. By choosing a special setup configuration, we have probed a field-induced energy scale that dominates in the vicinity of a node of the d-wave superconducting order parameter. We found a high doping sensitivity for this energy scale. At optimum doping, this energy scale is in agreement with an induced idxy order parameter. We found that it can be followed down to low fields at optimum doping but not away from it.
