Unusual features in the nonlinear microwave surface impedance of Y-Ba-Cu-O thin films
A. P. Kharel, Anton V. Velichko, J. R. Powell +3
Striking features have been found in the nonlinear microwave (8 GHz) surface impedance of high-quality YBaCuO thin films with comparable low power characteristics…
Non-linear Microwave Surface Impedance of Epitaxial HTS Thin Films in Low DC Magnetic Fields
A. P. Kharel, K. H. Soon, J. R. Powell +4
We have carried out non-linear microwave (8 GHz) surface impedance measurements of three YBaCuO thin films in dc magnetic fields (parallel to c axis) up to 12 mT using a c…
Modelling the Nonlinear High-Frequency Response of a Short Josephson Junction under Two-Frequency Irradiation
Anton V. Velichko, Adrian Porch
The nonlinear response of a short Josephson Junction (JJ), being irradiated simultaneously with two high-frequency signals, has been studied in the framework of the nonlinear Resis…
Phenomenological Model of the Nonlinear Microwave Response of a Superconductor Containing Weak Links
Anton V. Velichko, Adrian Porch
A phenomenological model is proposed which describes the effect of both dc and rf magnetic fields, , on the microwave surface impedance, Z_s=R_s+jX_s, of a superconductor contai…
