Progress in modern, widely-defined information technology is strongly determined by the abilities of detailed characterization of semiconductors, phosphors and composite materials in the wide range of anticipated parameters. Traditional electronics use an electron charge as a primary means for information data computing and storage. In contrast, spintronics utilizes the manipulation of an electrons spin which may facilitate opportunities implementing concepts and applications at nanoscale. In order to pursue spintronics realization, novel magnetic materials are required. One way to study magnetic materials is to observe their magneto-optical properties. Through this way, one can study how light interacts with magnetically active materials in the presence of a magnetic field. In general, in this project we are interested in observing the effect of photons electron spin interaction interceded through spin-orbit combination. This MS project targets developing of experimental setup suitable for studying materials in magnetic field strength up to 1.5 Tesla and light probe with photons energies between 4 eV (UV) to 1 eV (NIR) in temperature range from 7 K to 450 K, respectively. In particular, I will demonstrate my efforts on developing, testing and optimization of existing experimental setup for measuring Magneto Optical Kerr Effect (MOKE), Magnetic Circular Dichorism (MCD) and temperature dependent luminescence with magnetic field stimuli (Magneto Optical (MO) effect). Selection of samples were tested using developed apparatus including semiconductors crystalline GaMnAs (c-GaMnAs), amorphous AlN:Ni (a-AlN:Ni), polycrystalline KEu(WO4)2 phosphor. Additionally, this project demonstrates the successful construction and operation of developed magneto-optical characterization facility by measuring MOKE, MCD and magnetic field dependent luminescence for studied materials.
