[en] 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 x 10-3< (T/sub c/-T)/T/sub c/<5 x 10-2
