In superconductivity, a Semifluxon is a vortex of supercurrent carrying the magnetic flux equal to the half of the magnetic flux quantum. Semifluxons exist in the so-called 0-π long Josephson junctions at the boundary between 0 and π regions.
For the first time semifluxons were observed using d-wave superconductors at so called tricrystal grain boundaries and later in YBa2Cu3O7–Nb ramp zigzags. In these systems the phase shift of π takes place inside the d-wave superconductor and not at the barrier.
