Abstract(in English) | Effect of thermal noise on the voltage versus flux(V-Φ))relation of dc superconducting quantum interference devices(SQUIDs)is studied.A theoretical expression for the modulation voltage ΔV in the V-Φ relation is presented as a fnction of SQUID inductance.Tne theoretical expression is compared with experimental results of Δ V reported recently for high Tc SQUIDs with different inductances. It is shown that experimental results agree quanbitatively with theoretical ones.It is also shown that imperfection of Josephson junctions degrades the modulation voltage more significantly when the inductance increases.Finally,a new SQUID using three junctions is proposed in order to prevent degradation of the modulation voltage due to thermal noise.Numerical simulation shows the usefulness of the new SQUID,especially for the case of large inductances. |
