Abstract

Tunneling spectroscopy was performed on in-plane oriented [100] Y1Ba2Cu3O7-x/In tunnel junctions. Splitting of the zero-bias conductance peak at zero magnetic field was observed below 6 K. The splitting increases initially at the rate of 1.3mV/T when the field is applied along the [001] direction, and at a rate of 0.09mV/T and 0.11mV/T when applied parallel to the [010] and [100] directions, respectively. In the [001] direction, at 4.2 K, a sharp transition is seen at a field of about 0.8 T, from a rapid to a slow increase of the splitting. In that orientation, the splitting shows a large magnetic hysteresis.
