Description

This paper reports on properties of the dc SQUIDs made of YBCO thin film deposited on ZrO2 bicrystal substrate and nature of the fabricated Josephson junctions. 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 5 x 10-4 XX0/Hz1/2 and magnetic field sensitivity δB ∼ 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
