Microwave response of vortices in superconducting thin films of Re and Al
C. Song, T. W. Heitmann, M. P. DeFeo +5
Vortices in superconductors driven at microwave frequencies exhibit a response related to the interplay between the vortex viscosity, pinning strength, and flux creep effects. At t…

Picovoltmeter for probing vortex dynamics in a single weak-pinning Corbino channel
T. W. Heitmann, K. Yu, C. Song +4
We have developed a picovoltmeter using a Nb dc Superconducting QUantum Interference Device (SQUID) for measuring the flux-flow voltage from a small number of vortices moving throu…

Asymmetric weak-pinning superconducting channels: vortex ratchets
K. Yu, T. W. Heitmann, C. Song +4
The controlled motion of objects through narrow channels is important in many fields. We have fabricated asymmetric weak-pinning channels in a superconducting thin-film strip for c…
