Microwave Measurements on YBaCuO Thin Films and Realisation of Microwave Superconducting Devices

Two characterisations methods in microwaves are presented. They permit to obtain IS*, Rs and h for a HTS film without the need of any theoretical model for the superconductivity. The best film tested exhibits at 35GHz and 78K a Rs value of LO&. at least three times lower than the copper one. A quasi-integrated oscillator has been realised on a lcm2 area: it oscillates at 12GHz and close to liqu...

A ug 2 00 1 Magnetic relaxation and critical current density of MgB 2 thin films

Magnetic relaxation and critical current density have been measured on a M gB 2 thin film in a wide region of temperature with the magnetic field up to 8 T. The irreversibility line has also been determined. It is found that the relaxation rate has a very weak temperature dependence below 1/2T c showing a clear residual relaxation rate at zero K, which cannot be easily explained as due to therm...
