Resonant modes in small inductance superconducting interferometers

The magnetic field dependence of resonant modes in small inductance two‐junction interferometers has been investigated. Both symmetric and asymmetric configurations with equal and different junction size, respectively, have been considered. The experimental data have been compared with the theoretical dependence computed by a simple model of a single junction with a current density peaked at the edges. This model also takes into account the effects due to the field coupled with the junctions. An excellent agreement has been found between theoretical and experimental data.
