    • Abstract


      The results of the study of dc interferometers and SQUIDS from the thick-film YBa1·5Ca0·5Cu3O7\t-\gd 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 withinδɛn=10−28 to 10−29 J/Hz.
