Abstract

We studied the tunneling density of states of YBCO films at high magnetic field up to 15 Tesla parallel to the films' surface and perpendicular to the CuO2 planes. We observed a transition in the tunneling conductance at high fields. At 6 Tesla in increasing magnetic fields, the gap-like feature shifts discontinuously from 15meV to a lower bias of 11meV, and becoming more pronounced as the field increases. We found the effect to be anisotropic. We discuss its origin in term of current and/or magnetic field.
