Engineering Nonlinear Response of Superconducting Niobium Microstrip Resonators via Aluminum Cladding
Sangil Kwon, Yong-Chao Tang, Hamid R. Mohebbi +3
In this work, we find that Al cladding on Nb microstrip resonators is an efficient way to suppress nonlinear responses induced by local Joule heating, resulting in improved microwa…

Magnetic Field Dependent Microwave Losses in Superconducting Niobium Microstrip Resonators
Sangil Kwon, Anita Fadavi Roudsari, Olaf W. B. Benningshof +8
We describe an experimental protocol to characterize magnetic field dependent microwave losses in superconducting niobium microstrip resonators. Our approach provides a unified vie…

Vortex lattice dynamics in a-NbGe detected by mode-locking experiments
R. Besseling, O. Benningshof, N. Kokubo +1
We observed mode-locking (ML) of rf-dc driven vortex arrays in a superconducting weak pinning a-NbGe film. The ML voltage shows the expected scaling with t…
