【 摘 要 】

The magnetic interference pattern and the spontaneous Aux in unconventional Josephson junctions of superconductors with d+ is symmetry are calculated for different reduced junction lengths and the relative factor of the d- and s-wave components. This is a time-reversal broken symmetry state. We study the stability of the fractional vortex and antivortex which are spontaneously formed and examine their evolution as we change the length and the relative factor of d- and s-wave components. Asymmetry in the field-modulated diffraction pattern exists for lengths as long as L=10 lambda(J).
