Anomalous periodicity of magnetic interference patterns in encapsulated graphene Josephson junctions
We investigate supercurrent interference patterns measured as a function of magnetic field in ballistic graphene Josephson junctions. At high doping, the expected Φ_{0}-periodic “Fraunhofer” pattern is observed, indicating a uniform current distribution. Close to the Dirac point, we find anomalous i...
