摘要：

Periodic oscillations in the V-PHI characteristics have been observed up to 97 K in radio frequency SQUIDs fabricated from screen printed Bi-Sr-Ca-Cu-O thick films. The SQUID has been operated successfully in the flux-locked-loop mode at 77 K. Stability of the SQUID output and its noise performance have been found to improve considerably when the SQUID is operated in the flux-locked-loop mode as compared to that in the open-loop mode. The spectral noise density, in the white noise region, is 5 X 10(-4) PHI-0/square-root Hz at 77 K for the flux-locked-loop mode.
