  • Abstract
    The calculation of n-junction SQUID characteristics is simplified and other methods of calculation of SQUID are proposed. The effectiveness of SQUID self-shielding is shown. The magnetometer which is made on such nonshunted SQUIDs has flux resolution 3×10-3φ0x Hz-1/2. A process for SQUID fabrication is based on the use of Nb-NbOx-Pb(Bi) Josephson junction with Rj/R_{N}\\geq 18 , Nb ground plane, Al2O3insulated films, ion cleaning. Tunnel spectroscopy studies have indicated the correlation between oxide composition and oxidation temperature.
