$S-N-D$ corner junctions in magnetic field

The dependence of the critical current of a highly transparent $S-N-D$ corner junction on the applied magnetic field is determined for different orientations of a $d$-wave superconductor relative to the interface plane. It is shown that this dependence exhibits characteristic plateaus in a certain range of magnetic fields at low temperatures. These plateaus do not appear in the $S-N-S$ corner junctions, indicating the presence of a superconductor with a sign-variable order parameter.
