Kinetic-inductance Parametric Amplification in Superconducting Hybrid Magnonics

Parametric amplification enables sensitive microwave detection and signal processing by amplifying weak signals with minimal added noise. Here, we demonstrate kinetic inductance mediated parametric amplification in a hybrid magnonic system comprising a nonlinear NbN nanowire resonator strongly coupled to a yttrium iron...

Control of disorder and superconductivity in sputtered TiN thin films via substrate RF bias

Titanium nitride thin films are prepared using DC reactive magnetron sputtering at room temperature, with an RF bias applied to the substrate to systematically control film growth. By adjusting the substrate RF bias, the degree and length scale of disorder are tuned, leading to pronounced changes in film microstructure...
