Important for the understanding of the origin of magnetic properties and for the technological applications of magnetic materials is the ability to observe magnetic domains and domain wall structures. One common domain observation method is magneto-optical microscopy. The wide-field magnetic microscopy technique is based on the Kerr and the Faraday effect.

Recent advances and applications of wide-field magneto-optical microscopy will be reviewed. The versatility and possibilities of the method will be illustrated. Examples include regular quasi-static imaging, quantitative dual wave-length domain imaging, as well as dynamic domain imaging with picosecond resolution. Beyond domain imaging, the use of magneto-optical microscopy for the laterally and time-resolved imaging of temperature fields will be demonstrated.
