Magneto-optical imaging of a photo-induced change in magnetization in (Ga,Mn)As is accomplished for the first time by using a scanning laser magneto-optical microscope. Observed results clearly show the importance of excitation with circularly polarized light. The micron-scale imaging reveals that details of photo-induced change depend not only on excitation condition but also on the initial magnetization state. (© 2006 WILEY-VCH Verlag GmbH & Co.
