Abstract
We have fabricated and measured optimized SQUID sensors (superconducting quantum interference device) for low frequency measurements of magnetic field. We have also investigated the dependence of flux trapping field on the position of Josephson junctions with respect to the Ketchen-type washer.
The sensors are measured using direct room temperature readout utilizing noise cancellation techniques based on negative and positive feedback.
A superconducting magnesium diboride can is used to shield the sample in pulse-tube cryocooler measurements.
