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. 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

5. 4. Fabrication and characterization of novel nano-magnets

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

   Author : Louise Lifvenborg; [2020]
   Keywords : nanotechnology; nano-magnets; magnetism; Master s Programme in Materials Engineering; Q; lithography;

   Abstract : Magnetic data storing has been of great interest since 1950 when the first magnetic hard drive was fabricated. A lot has happened since then, but there is still a need for smaller and cheaper devices.  One way to achieve this is by creating nano-sized ferromagnetic areas in a thin film at room temperature, or nano-magnets.

6. 5. Tailoring the magnetic anisotropy in amorphous FeZr-based thin films on flexible and solid substrates

   University essay from

   Author : Matteo Menniti; [2018]
   Keywords : amorphous; magnetic; materials; anisotropy; material characterization; iron; cobalt; zirconium; boron; moke; magneto optical; tailoring; material design; flexible; magnetostriction; functional materials; sensor;

   Abstract : In this thesis the magnetic properties of novel amorphous magnetic materials grown on a flexible substrate of polyethylene naphthalate and a silicon wafer have been analyzed and characterized. The analyzed films are two films of amorphous Cobalt-Iron-Zirconium(Co36Fe53Zr11 & Co37Fe55Zr8) grown on the flexible substrate and two films of amorphous (Fe89Zr11) doped with boron (B). READ MORE
