Imaging phase slip dynamics in micron-size superconducting rings
Imaging phase slip dynamics in micron-size superconducting rings
We present a scanning probe technique for measuring the dynamics of individual fluxoid transitions in multiply connected superconducting structures. In these measurements, a small magnetic particle attached to the tip of a silicon cantilever is scanned over a micron-size superconducting ring fabricated from a thin aluminum film. We find that …
