摘要：
The results of the study of dc interferometers and SQUIDS from the thick-film Y1Ba2Cu3O7-delta ceramics are presented here. It is shown that under the influence of high-density currents 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 delta-epsilon-n = 10(-28) to 10(-29) J/Hz.
