20.500.12556/RUL-120458 Optično merjenje ultrahitre magnetne dinamike Optical measurement of ultrafast magnetization dynamics Eden iz med temeljev tehnološkega razvoja so magnetne snovi, zato je potrebno take snovi preučevati in odkrivati njihove lastnosti. Za raziskovanje ultrahitre dinamike magnetnih snovi je potrebno uporabiti primeren eksperimentalni sistem, ki nam omogoči vpogled v ultrahitro magnetno dinamiko pod različnimi pogoji. Eden izmed možnih načinov je optično merjenje magnetne dinamike. Tak eksperimentalni sistem sestavlja sunkovni laser, kriostat v kateremu spreminjamo temperaturo magnetne snovi, detektor svetlobe in elektronsko vezje. V zaključni nalogi smo z eksperimentalnim sistemom raziskovali ultrahitro magnetno dinammiko v kristalu CeSb. S spreminjanjem temperature in magnetnega polja smo spreminjali zunanje pogoje in vpliv teh sprememb izmerili z optično vzbujevalno-testno spektroskopijo. 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.
