摘要：

Inductive reply of the high Tc rf SQUIDs were investigated at 77 K. It is shown experimentally that the SQUIDs operate in adiabatic nonhysteretic (dispersive) mode. The SQUIDs were operable even if (i) the Josephson coupling energy is considerably smaller than the thermal energy, and (ii) the SQUID inductance as larger than the so called ''fluctuation-threshold inductance''. The influence of thermal noise on the response of nonhysteretic SQUIDs is estimated theoretically. The validity limits of the estimation are discussed.
