  This letter discusses the Landau Ginzburg theory of a Josephson junction
composed of on one side a pure d-wave superconductor oriented with the $(110)$
axis normal to the junction and on the other side either s-wave or d-wave
oriented with $(100)$ normal to the junction. We use simple symmetry arguments
to show that the Josephson current as a function of the phase must have the
form $j(\phi) = j_1 \sin(\phi) + j_2 \sin(2 \phi)$. In principle $j_1$ vanishes
for a perfect junction of this type, but anisotropy effects, either due to a-b
axis asymmetry or junction imperfections can easily cause $j_1 / j_2$ to be
quite large even in a high quality junction. If $j_1 / j_2$ is sufficiently
small and $j_2$ is negative local time reversal symmetry breaking will appear.
Arbitrary values of the flux would then be pinned to corners between such
junctions and occasionally on junction faces, which is consistent with
experiments by Kirtley et al.
