Description

We have realized reliable DC-SQUIDs in aluminium with two Dayem bridges in only one lithographic operation. These bridges appear to behave like classic Josephson junctions even at low temperature far from Tc. They are very durable and reproducible upon temperature cycling. They exhibit a considerable hysteresis and critical curents as low as 10 μA. An electronic setup has been developed in order to measure the critical current of these hysteretic SQUIDs with a typical noise of 8 10-6Φ0/Hz1/2. This non-destructive and damage free technique allows one to perform magnetization measurements on any material. (orig.)
