摘要: This letter reports measurements down to 3 mK of the magnetic field dependence resistance and critical current a weakly coupled periodic array Josephson junctions. Below 700 is an oscillatory function field. The temperature for integral numbers flux quanta per cell suggests existence Kosterlitz-Thouless transition involving unbinding defects in lattice.
