Magnetic field behavior of a Josephson-junction array: Two-dimensional flux transport on a periodic substrate
Journal Article
·
· Phys. Rev. Lett.; (United States)
This letter reports measurements down to 3 mK of the magnetic field dependence of the resistance and critical current of a weakly coupled periodic array of Josephson junctions. Below 700 mK the resistance is an oscillatory function of field. The temperature dependence of the resistance for integral numbers of flux quanta per cell suggests the existence of a Kosterlitz-Thouless transition involving the unbinding of defects in the flux lattice.
