1. 1. Magnetization dynamics in bistable systems

   University essay from Uppsala universitet/Materialfysik

   Author : Sven Backlund; [2023]
   Keywords : magnetism; magneto-optics; magnetization dynamics;

   Abstract : The magnetization dynamics in ferromagnetic materials will depend on the specific shape of the system’s energy landscape. In most systems, the energy landscapes can be approximated as paraboloids, resulting in a typical ellipti- cal precession of the magnetization. READ MORE

3. 2. 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

4. 3. 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

5. 4. Modeling of optical microresonator frequency combs

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

   Author : Michael Ekström; [2022]
   Keywords : Optical frequency combs; Nonlinear optics; Temporal cavity solitons;

   Abstract : An optical frequency comb is a structure of equidistant, coherent spectral components which can be thought of as a large array of individual phase-locked laser sources. Their utilization in precision spectroscopy garnering part of the 2005 Nobel prize, optical frequency combs constitute a relatively novel technology with a large number of potential and actual applications.

6. 5. The Effect Of Sub Tx Heat Treatments On The Magnetic Properties Of An Fe-based Bulk Metallic Glass

   University essay from Uppsala universitet/Materialfysik

   Author : Grunditz Jakob; [2022]
   Keywords : Bulk metallic glass; annealing; heat treatment; MOKE; Magnetic; Fe-based; Coercivity; Magnetic properties; Magnetic saturation; coercivity; saturation; magnetic coercivity; sub crystallization; sub Tx; Relaxation;

   Abstract : Metallic glasses produced with Selective Laser Melting (SLM) often contain internal mechanic stress. This internal stress can have an impact on the magnetic properties of the material due to its connection to the magnetic anisotropy of the material. READ MORE
