Abstract

PURPOSE:To eliminate a resistance element used normally in a Josephson interference meter circuit by employing solid solution of lead and indium for a superconductive substance forming the electrode of the Josephson element and controlling the composition of the solid solution when forming the circuit with the Josephson element and an inductance element. CONSTITUTION:Josephson junction elements J1, J2 are connected by using an inductance element L1, and a bias current line 1 is connected to the closed loop having the elements. Further, an inductance element L2 connected to a control current line 2 is connected to the element L1 as a Josephson interference meter circuit M. When a resistance element is normally connected to the elements J1, J2 normally in this structure, superconductive substance electrodes 11, 13 disposed between the tunnel barrier layers 12 of the elements J1, J2 are formed of solid solution of lead and indium selected in weight ratio, and a resistance element is thus eliminated. Thus, there can be obtained a desired braking coefficient while simplifying the circuit configuration of the Josephson interference meter circuit.
