摘要：
We have fabricated de-superconducting quantum interference devices (SQUIDs) with all-thin-film point contacts (Nb-Nb nanoconstriction-NbN). The size of the nanoconstriction may be smaller than the superconducting coherence length of bulk Nb. The quasiparticle characteristic of the all-thin-film point contact can be explained using the Blonder, Tinkham and Klapwijk (BTK) quasiparticle current which is applicable to the superconducting quantum point contact. The flux noise of SQUID with 10 pH operated in a flux locked loop is 8 mu Phi(0)/Hz(1/2) at 1 Hz, and 4 mu Phi(0)/Hz(1/2) at frequencies above 10 Hz is limited by the preampiifier.
