Nonlinear microwave response of epitaxial YBaCuO films of varying oxygen content on MgO substrates
M. A. Hein, R. G. Humphreys, P. J. Hirst +2
We have investigated the nonlinear microwave properties of electron-beam coevaporated YBaCuO films on MgO, using stripline resonators at 2.3 GHz and temperatures 1.7-80 K. The oxyg…
Recent developments in the characterization of superconducting films by microwaves
M. A. Hein, M. Getta, S. Kreiskott +7
We describe and analyze selected surface impedance data recently obtained by different groups on cuprate, ruthenate and diboride superconducting films on metallic and dielectric su…
Nonlinear Dielectric Microwave Losses in MgO Substrates
M. A. Hein, D. E. Oates, P. J. Hirst +2
We have investigated the nonlinear surface impedance and two-tone intermodulation distortion of nine epitaxial YBa2Cu3O7-d films on MgO substrates, using stripline resonators, at f…
Anomalous Nonlinear Microwave Response of Epitaxial YBa2Cu3O7-x Films on MgO
M. A. Hein, P. J. Hirst, R. G. Humphreys +2
We have investigated the anomalous nonlinear microwave response of epitaxial electron-beam coevaporated YBa2Cu3O7-x films on MgO. The power and temperature dependent surface impeda…
