Thermally activated vortex motion in YBa2Cu3O7 wire networks

With a mutual inductance method we have measured the temperature dependence of the complex AC impedance Z = R + iωL of high quality YBa2Cu3O7 wire networks. In a perpendicular magnetic field the real and the imaginary part of Z exhibit oscillations resulti ...

Range of Applicability for the Critical State Model and the Interaction between the Abrikosov and Josephson Vortices

Alexander Tagantsev

The minimal a.c. magnetic field which is able to penetrate into the hollow ceramic Y-Ba-Cu-O cylinder was studied experimentally and theoretically as a function of the d.c. magnetic field. The critical state model predicts reversible dependence on the d.c. ...

Magnetoconductance oscillations in high temperature superconducting networks

Philippe Flückiger

The complex AC impedance Z of superconducting YBa2Cu 3O7 triangular networks exposed to a perpendicular magnetic field was measured with a two-coil mutual inductance technique. At temperatures close to the transition temperature, both the imaginary and the ...

Dynamical study of the superconducting phase transition of two-dimensional networks

Philippe Flückiger

Granular aluminum wire networks forming square arrays of N×N=1E6 nodes connected by strips of 8-μm long were fabricated with photolithographic techniques. For strip resistances of the order of 1 kΩ the superconducting transition of the network, as evidence ...
