Development of high-
superconducting thick-film rf-SQUID sensors and their application in non-destructive testing
A K Gupta, Neeraj Khare and Sangeeta Khare
Show affiliationsRadiofrequency-SQUID (superconducting quantum interference device) sensors have been fabricated using natural grain boundary weak-links in high-
Br - Sr - Ca - Cu - O screen printed thick films. The films have predominantly high- 2223 phase and are c-axis oriented with large size grains (
- 
) and 
of 104 K. These sensors showed good voltage - flux (V - 
) characteristics at 77 K. The rf-SQUIDs have been operated in the flux-locked-loop mode at 77 K and showed a flux noise density 
in the white noise region. The potential of these SQUIDs in non-destructive detection of defects in steel plates has been demonstrated.
