Abstract
We present here a new experimental tool for the direct observation of magne tic vortices in type-II superconductors. The magneto-optical imaging techni que has been improved to enable single vortex observation at low flux densi ties. The main advantage of the new method is its high temporal resolution combined with the applicability to any superconducting sample with a flat s urface. We give a short description of the experimental set-up and show exa mples of results obtained for a NbSe2 single crystal at 4.0 K.
