  Studies of the magnetic interference of sandwich-type Josephson junctions in
which perpendicular or oblique magnetic fields are applied to the junction
plane have received less attention than those where the applied magnetic fields
are parallel. Recently, it has been theoretically demonstrated that a variety
of magnetic interferences of the critical currents appear when oblique magnetic
fields are applied to a cross-type junction with homogeneous critical current
density. We theoretically investigated the effect of the inhomogeneous critical
current density in the junction plane, and found that more complicated magnetic
interferences appeared. We considered the distribution of the current density
flowing through the junction plane to explore the cause of these complex
magnetic interferences.
