Abstract:
We have designed and fabricated a new type of highTc rf SQUID sensor. A high T c coplanar superconducting resonator and a large area high Tc superconductin g film concentrator have been used simultaneously. With a large effective area and low white flux noise, we have achieved a flux noise of 2.1×10-5 0 /Hz and a magnetic field sensitivity of 34fT/Hz in white noise range, respective ly, using an effective area of 1.27 mm2 concentrator on a 15 mm×15 m m substra te. This design can be easily applied to higher frequency high Tc rf SQUID system.
