  3. 2. Towards atomically resolved magnetic measurements in the transmission electron microscope : A study of structure and magnetic moments in thin films

    Författare :Hasan Ali; Klaus Leifer; Peter Van Aken; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscope; thin films; magnetic moments; electron energy loss spectroscopy; simultaneous acquisition; electron magnetic circular dichroism; Teknisk fysik med inriktning mot materialanalys; Engineering Science with specialization in Materials Analysis;

    Sammanfattning : The magnetic properties of thin metallic films are significantly different from the bulk properties due to the presence of interfaces. The properties shown by such thin films are influenced by the atomic level structure of the films and the interfaces. LÄS MER

  5. 4. Detailed structure features from 3D electron diffraction : Heteroatoms, framework disorders, and guest species in zeolites

    Författare :Jungyoun Cho; Xiaodong Zou; Tom Willhammar; Miguel Camblor; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron crystallography; zeolite; transmission electron microscope; structure determination; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : 3D electron diffraction (3D ED) has evolved as a powerful method for ab initio structure determination from sub micrometer-sized crystals. It can be used to elucidate the arrangement of atoms in crystalline materials and to provide insights into the laws of nature that govern the properties of matter. LÄS MER
