Abstract

We have developed a magneto-optical Kerr microscope that allows us to measure the ultrafast magnetization dynamics of ferromagnetic nanostructures. The magneto-optical signal can be recorded in a confocal reflection geometry with an accurate selection of the polarization. The magnetization dynamics is obtained from pump–probe measurements using frequency nondegenerate collinear pump and probe beams with a temporal resolution of 180 fs . Both probe and pump beams are focused to their diffraction limit, leading to an overall spatial resolution of 600 nm . The efficiency of the apparatus is tested by investigating the magnetization dynamics of individual Co Pt 3 disks with a submicrometer diameter and a thickness of 15 nm .
