  1. 11. PROCESSUTVECKLING FÖR JÄRNBASERADE HÅRDMAGNETISKA PULVER UTAN SÄLLSYNTA JORDARTSMETALLER

    University essay from Lunds universitet/Materialteknik

    Author : Per-Olof Andersson; [2014]
    Keywords : Crystalline metals; Magnetic materials; Hard magnetic materials; Electro-magnetic applications; Single crystalline powder; Powder metallurgy; Fe2B; FeB; Water atomization; Gas Water atomization; non-RE hard magnetic material.; Technology and Engineering;

    Abstract : 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

  3. 12. Magnetic grain-size analyses of Holocene sediments in the North Atlantic and Norwegian Sea : palaeoceanographic applications

    University essay from Lunds universitet/Geologiska institutionen

    Author : Torbjörn Wall; [2004]
    Keywords : magnetic grain-size; magnetic hysteresis loops; Reykjanes Ridge; Vøring plateau; North Atlantic; Norwegian Sea; deep ocean currents; Holocene; magnetisk kornstorlek; magnetiska hysteresis-lopar; Reykjanesryggen; Vøringplatån; Nordatlanten; Norska havet; djuphavsströmmar; Holocen; Earth and Environmental Sciences;

    Abstract : 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

  4. 13. A comparative study between loss on ignition and total carbon analysis on Late Glacial sediments from Atteköps mosse, southwestern Sweden, and their tentative correlation with the GRIP event stratigraphy

    University essay from Lunds universitet/Geologiska institutionen

    Author : Daniel-Stefan Veres; [2001]
    Keywords : Atteköps mosse; limnic sediments; Late Glacial; loss on ignition; total carbon; Earth and Environmental Sciences;

    Abstract : Popular abstract: In this study, several sediment core from Atteköps mosse, southwestern Sweden, were investigated with respect to lithostratigraphy, loss on ignition analysis, grain size distribution, magnetic susceptibility, total carbon analysis and 14C dating. The first part of the study foccuses on a detailed analysis of the above mentioned sediment parameters. READ MORE
