1. Preparation and Characterization of Tb-Co Magnetic Films
University essay from Uppsala universitet/MaterialfysikAbstract : 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

2. Investigation of Inverse Magnetostriction inCobalt Films and Nanowires
University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysikAbstract : 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

3. Tailoring the magnetic anisotropy in amorphous FeZr-based thin films on flexible and solid substrates
University essay fromAbstract : 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

4. PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER
University essay from Lunds universitet/MaterialteknikAbstract : An experimental study was performed, aimed at finding a way to produce single crystalline powder of pure (Fe0.7Co0.3)2B with a particle size of 100-200nm. This was done with the ultimate goal of producing a hard magnetic ferrite powder for powder metallurgical production of permanent magnets. READ MORE

5. Magnetic grain-size analyses of Holocene sediments in the North Atlantic and Norwegian Sea : palaeoceanographic applications
University essay from Lunds universitet/Geologiska institutionenAbstract : High-resolution magnetic hysteresis measurements were carried out on three sediment cores, one from the North Atlantic and two from the Norwegian Sea. These measurements can be used to reconstruct changes in magnetic grain-size. Physical grain-size has been interpreted as a proxy for bottom current intensity (McCave et al. READ MORE
