Abstract

The performance characteristics of Bi-Sr-Ca-Cu-O thick film radio frequency superconducting quantum interference devices (SQUID) in liquid nitrogen were evaluated. The results showed that the SQUID exhibited periodic oscillations up to 97 K in radio frequency. The device was successfully operated in the flux-locked-loop mode at 77K. Operation in this mode significantly improved stability and noise performance in the device.

Abstract

Thick films of Bi-Sr-Ca-Cu-O were deposited on (100) MgO substrates by screen-printing technique with the starting composition 1112. To attain the superconducting state, the films were subjected to two-step heat-treatment. R-T and XRD have been studied for films annealed at different durations of the second step. InitiallyTc(R=0) increased from 77 to 103 K as the annealing duration was increased after whichTcdecreased. Kinetics of the growth of highTcphase is discussed in the light of our results.
