Switching probabilities of magnetic vortex core reversal studied by table top magneto optic Kerr microscopy

We have studied vortex core reversal in a single submicron Permalloy disk by polar Kerr microscopy. A sophisticated lock-in-technique based on repetitive switching of the magnetic vortex core and a continuous calibration allows for a reliable determination of the switching probability. This highly s...
