One of fundations of technological development are magnetic materials. Its therefore necessary to investigate their properties.
For research of ultrafast magnetic dynamics of materials we need appropriate experimental system, which gives us ability to investigate their dynamics under different conditions. One of possibilities are optical measurements of magnetic dynamics. An optical experimental system is constructed from laser, cryostat, detector and electronics that sends us the results.
In bachelor thesis we researched ultrafast magnetical dynamics in a CeSb crystal with the mentioned optical experimental system. By means of the ultrafast time-resolved optical spectroscopy we measured signals that we got from the crystal under different external condtions.
