1. 1. A theoretical framework for interpretation and prediction of magneto-optical measurements

   University essay from Uppsala universitet/Materialteori

   Author : Viktor Frilén; [2023]
   Keywords : moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

   Abstract : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

3. 2. 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

4. 3. 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

5. 4. Tailoring the Magnetic Properties of Amorphous TbCo Nano Films

   University essay from Uppsala universitet/Materialfysik

   Author : Viktor Djurberg; [2018]
   Keywords : Magnetic properties; Amorphous TbCo film; Magnetic Anisotropy; Interface effects;

   Abstract : The possibility to change magnetic anisotropy of amorphous TbCo films from out-of-plane to in-plane has been investigated. The effects of TbCo film's thickness and composition on the magnetic anisotropy were investigated together with the effects of growing the TbCo films on a SmCo seed layer. READ MORE

6. 5. Optimisation of measuring magneticproperties of micro-structuresusing the magneto-optic Kerr effect

   University essay from Uppsala universitet/Materialfysik

   Author : Måns Persson; Filip Lindh; [2016]
   Keywords : moke; magnetism; elektromagnetism;

   Abstract : Magnetic storage means storage of data using magnetised medium and is widespreadover the world today, especially in hard disk drives. Using this kind of storagerequires knowledge about these materials. A way to study thin magnetic materials isto use MOKE(magneto optical Kerr effect). READ MORE
