  1. 6. Structure-Magnetic Relationships in the Fe-Mn-P-Si System for Energy Applications

    Författare :Viktor Höglin; Yvonne Andersson; Per Nordblad; Martin Sahlberg; Mogens Christensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetocaloric; X-ray powder diffraction; Neutron powder diffraction; Magnetization measurements; Phase diagram; Crystal structure; Magnetic structure; Incommensurate structure; Ferromagnetic; Antiferromagnetic; Fe2P; Fe-Mn-P-Si.; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

    Sammanfattning : Demands for new, energy-efficient appliances have greatly increased in response to our growing need for a more environmentally friendly society. Magnetic refrigeration is a technique that utilizes the magnetocaloric effect, with possible energy savings of up to 30% compared to commercial gas compression refrigerators. LÄS MER

  3. 7. Nanoscale studies of functional materials using scanning probe microscopy

    Författare :Jesper Wittborn; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis deals with developing suitable modifications ofScanning Probe Microscopy (SPM) for investigations offunctional properties of materials. In order to make itpossible to investigate a number of properties of variousfunctional systemsusing SPM the following new techniques have beendeveloped:    A magnetic force microscope (MFM) having capability ofboth dc- and ac-mode detection.
