Josephson-like behavior in double Dayem bridge structures

Abstract
The behavior of a pair of aluminum ’’Dayem’’ bridges in a magnetic field is reported. The quantum interference properties of the supercurrents are found biasing the links with an ac current and measuring its mean square voltage as a function of an external magnetic field. The shape of the so‐obtained curve remains the same in a relatively large range of temperature: 6×10−3< (TcT)/Tc−2.
