Abstract

The properties of a one-dimensional 0-π-Josephson junction, consiting of an s-d junction or selected boundaries between three suitably oriented d-wave superconductors, are studied. It is shown that a d-wave type interference pattern can only be observed in the field-modulated critical current if the junction is short compared to the Josephson penetration depth. However, the behavior of a 0-π junction is found to be indistinguishable from that of a 0-junction between s-wave superconductors in the long junction limit, due to the formation of a π-vortex.
