【 摘 要 】

We propose a simple experiment to determine whether vortices persist above the superconducting transition temperature T-c in the pseudogap phase of high-temperature cuprate superconductors. This involves using a magnetic dot to stabilize a vortex in a thin cuprate film beneath the dot. We calculate the magnetic field profile as a function of distance from the dot if a vortex is present and discuss possible measurements that could be done to detect this. Finally, we comment on the temperature range where a stable vortex should be observable.
