Description

The results of the study of dc interferometers and SQUIDS from the thick-film Y1Ba2Cu3Osub(7-δ) ceramics are presented here. It is shown that under the influence of high-density current through the film constriction the differential resistance of interferometers thus formed increases by 2-3 orders of magnitude and the voltage-field characteristics become more regular. The frequency dependence of intrinsic noise in dc SQUIDs based on thick-film interferometers is investigated. It is demonstrated that in the white noise frequency region (1-10 Hz) the energy sensitivity is within δεn=10-28 to 10-29J/Hz. (author). 4 refs., 3 figs
