dc.description.abstractTitle: Optical spectroscopyof magnetic nanostructures Author: Eva Liskova Department: Fyzikalni Ostav Univerzity Karlovy Supervisor: Prof. Ing. Stefan Visnovsky, DrSc. Supervisor's e-mail address: visnov@karlov.mff,cuni.cz Abstract: Magnetic oxide nanostructures of La2/3Sri/3Mn03, BixYi.xFe5012 and Fe304 were investigated using magneto-optical reflection spectroscopic ellipsometry in the photon energy range between 1 and 5 eV. The samples were grown using MBE (Molecular Beam Epitaxy) and PLD (Pulsed Laser Deposition). Their spectroscopic studies were focused to the effects of growth conditions, substrate crystallographic orientation as well as those of subsequent heat treatment in oxygen. Thanks to this selective approach, largely eliminating substrate contribution, relevant information on physical properties of the low volume samples was obtained. Note that ordinary structural and magnetic metrologies suffer of reduced sensitivity due to the dominating effect of bulky substrates. The research was motivated by practical applications of the investigated nanostructures in spin electronics, reading high density magnetic disks, in nonreciprocal optoelectronics devices, magneto-optical light modulators, and megnetophotonic crystals. In addition, the physical properties of magnetite present interest for the use...en_US
