We report results obtained with two different experimental set-ups in state-of-the-art YBCO thin films as similar as possible, prepared by pulsed laser deposition on LaAlO3 substrates: a surface impedance measurement on 4000 A thick films using a par

The parallel plate resonator method has been used for measuring high quality YBa 2 Cu 3 O 7− x (YBCO) thin films. The surface resistance and the real part of the conductivity show a non-monotonic behaviour with a broad peak around 45 K. The penetra

This report presents a study of the temperature dependence of the penetration depth in Y 1− x Ca x Ba 2 Cu 3 O 7− δ thin films, which shows that a contribution to the order parameter from phase fluctuations in optimally doped samples cannot be e

In order to develop superconducting thin films or multilayer structures suitable for Superconducting Flux Flow Transistors (SFFTs), we propose a model to describe the current–voltage characteristics measured on microbridges in the flux creep regime

The connection between the effect of a uniform magnetic field on the I-V curves measured on the microbridges of superconducting flux flow transistors and the vortex dynamics is studied with the help of a model assuming that the motion of the vortices

We found that the current–voltage characteristics measured on La0.66Sr0.33MnO3∕YBa2Cu3O7−δ thin film heterostructures patterned as microbridges are nonsymmetric if the magnetization direction of the La0.66Sr0.33MnO3 film is in plane and perpen

The growth of Bi4Cu2xV2(1-x)O11 thin films by pulsed laser deposition (PLD) is reported for the first time. Samples with x = 0.1 are grown on polycrystalline BeO and (100) MgO substrates. Films show lattice parameters a = b = 3.926 A and c = 15.491 A

We propose a mean field description of the phenomena occurring in superconducting thin film microbridges with low pinning forces when vortices are nucleated. This model allows for computation of the vortex velocity, the penetration depth, the critica

The surface impedance for various doping of Y1-xCaxBa2Cu3O7-? thin films was studied at 10GHz using the Parallel Plate resonator. In addition the complex dielectric function was measured using a FIR transmission up to 1THz as a complementary method.
