Single-pulse magneto-optic microscopy: a new tool for studying optically induced magnetization reversals.
We have developed a femtosecond magneto-optical imaging system that allows measurements of permanent magnetic effects that are initiated by a single excitation pulse. The system combines a subpicosecond temporal resolution and a high spatial resolution. We demonstrate the system in an experiment that studies the laser-induced magnetization reversal in ferromagnetic thin films.
