Designing phase-sensitive tests for Fe-based superconductors
  We suggest new experimental designs suitable to test pairing symmetry in multiband Fe-based superconductors. These designs are based on combinations of tunnel junctions and point contacts and should be accessible by existing sample fabrication techniques.
