Аннотация:Properties of the dc SQUIDs made of YBCO thin film deposited on ZrO2 bicrystal substrate and nature of the fabricated Josephson junctions have been studied. It is found that the characteristics of the junctions are similar to that of the SNS structures with paramagnetic impurities in the N layer. The level of the interferometer noise close to 5x10(-4) PHI-o/Hz1/2 and magnetic field sensitivity delta-B approximately 10(-10) T/Hz1/2 at frequencies higher than 25 Hz in the usual feedback mode of the SQUID operation has been achieved at 77 K.
