Description

We review r.f. measurements of the surface impedance Zs=Rs+iXs of YBCO films films deposited on sapphire or MgO . The measurements are performed by a microstrip dielectric resonator and cavities techniques using a meander line geometry. The power dependence of Zs is studied at different temperatures and frequencies in the range 1-18 GHz. The effects of a d.c. magnetic field applied with different orientations is also studied. The data are analyzed in the context of different models . The data will be discussed for possibile interest for different application including ollective coupling with spin ensembles and MASER
