Low-temperature electron dephasing rates indicate magnetic disorder in superconducting TiN films
A. I. Lomakin, E. M. Baeva, N. A. Titova +8
We investigate electron transport and phase-breaking processes in thin titanium nitride (TiN) films of epitaxial quality. Previous studies show that a minute surface magnetic disor…

Accurate measurement of energy relaxation via flux-flow instability
E. M. Baeva, N. A. Titova, M. A. Kirsanova +5
In this paper, we investigate flux-flow instability (FFI) in a superconducting single-crystal titanium nitride (TiN) film with negligible volume pinning. By studying the critical c…

Slow electron-phonon relaxation controls the dynamics of the superconducting resistive transition
E. M. Baeva, A. I. Kolbatova, N. A. Titova +8
We investigate the temporal and spatial scales of resistance fluctuations (-fluctuations) at the superconducting resistive transition accessed through voltage fluctuations measu…
