1. 1. Development of MOKE spectrometer

   University essay from Uppsala universitet/Materialfysik

   Author : Sebastian Åberg; [2023]
   Keywords : MOKE; Spectroscopy;

   Abstract : The magneto-optical Kerr effect (MOKE) describes the change in polarization of light reflected from a magnetic surface. This change is proportional to the magnetization and depends on the wavelength of light. Because of these properties, MOKE has found use as a tool to probe magnetism in matter. READ MORE

3. 2. Preparation and Characterization of Tb-Co Magnetic Films

   University essay from Uppsala universitet/Materialfysik

   Author : Roméo Beignon; [2022]
   Keywords : Thin Film; TbCo; Out-of-Plane Anisotropy; Magnetic Domains;

   Abstract : Thin films of terbium-cobalt alloy have been deposited by magnetron sputtering. They exhibit an out-of-plane magnetic anisotropy that may result in elongated domains. The effect of thicknesses and compositions on the domain structure has been studied systematically. READ MORE

4. 3. A study of optical and structural properties of spin-coated V2O3 thin films on sapphire substrates

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Jennifer Silander; [2022]
   Keywords : Optical properties; transmittance; FTIR spectrometry; scanning electron microscopy; x-ray diffraction; metal-insulator transition; crystalline material; sol-gel; spin-coating; vanadium oxide; infrared light;

   Abstract : Many transition metal oxides exhibit a Metal-Insulator Transition (MIT). This is an interesting phenomenon where the material undergoes a structural phase transition, and the electronic charge is redistributed in the crystal lattice. READ MORE

5. 4. Investigation of Inverse Magnetostriction inCobalt Films and Nanowires

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Author : Ahmad Montaser Lababidi; [2020]
   Keywords : ;

   Abstract : In this thesis, a study of the inverse magnetostriction (the Villari effect) of Co nanowires and films is presented. The main objective was to investigate the stability of the Co nanowires’ magnetic properties, i.e. READ MORE

6. 5. Modelling a Novel Linear Transverse Flux Machine and Designing a Hysteresis Current Controller for Power Factor Correction

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ahmed Alhaidari; [2019]
   Keywords : double band hysteresis current controller; linear machine; magnetic circuit model; power take-off; transverse flux permanent magnet synchronous machine; wave energy conversion;

   Abstract : In this thesis, the basics of electromagnetic theory for wave-energy conversion are reviewed, some of the characteristics of the ocean wave are investigated, some of the power take-off (PTO) systems are introduced, and details about linear permanent magnetic machines, in particular, are discussed.  The thesis aims to model the novel linear transverse flux machine designed by Anders Hagnestål and to build hysteresis current controller for power factor correc- tion.
