Nonreciprocal supercurrent phenomena and the corresponding diode effect in dc SQUIDs based on Josephson junctions with single and multiband superconductors are studied. It is shown that magnetic fields can independently control supercurrent rectification’s amplitude and direction, particularly in superconductors with broken time-reversal symmetry.
