N2 - Relaxation oscillation SQUIDs (ROSs) based on Nb/Al, AlOx/Al/Nb Josephson tunnel junctions have been designed and fabricated. The hysteretic SQUIDs (superconducting quantum interference devices) have a maximum critical current of about 130 μA and an inductance of 20 pH. A voltage modulation of 40 μV and a flux to voltage transfer δV/δΦ of 4 MV/Φ0 have been measured in these SQUIDs. Double relaxation oscillation SQUIDs (DROSs), which are based on two hysteretic SQUIDs, showed transfer coefficients up to 77 mV/Φ0. The intrinsic white flux noise of the DROSs is smaller than 3-5 μΦ0/√Hz. It is noted that the results are very promising for a next generation of SQUID systems with simplified read-out.
