  1. 1. Ultrafast resonant magnetic scattering at the European XFEL

    Författare :Nanna Zhou Hagström; Stefano Bonetti; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; XFEL; ultrafast magnetism; holography; SAXS; fysik; Physics;

    Sammanfattning : Magnetic materials are of interest in a wide range of nanotechnologies such as for data storage, memory, logic, and sensing applications. Today, there is a strong desire to manipulate magnetism at timescales below the picosecond. There is therefore a high motivation in studying ultrafast magnetism at the nanoscale. LÄS MER

  3. 2. Ultrafast spin dynamics at the nanoscale : using coherent X-ray and terahertz radiation

    Författare :Nanna Zhou Hagström; Stefano Bonetti; Stefan Eisebitt; Ferran Macià Bros; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; XFEL; small-angle X-ray scattering; X-ray holography; ultrafast magnetism; symmetry-breaking; magnetic domains; terahertz; magnetic field enhancement; metamaterial; time-resolved magneto-optical microscope; Physics; fysik;

    Sammanfattning : The field of ultrafast magnetism is driven by the growing need for faster and more efficient magnetic data storage, which comprises the vast majority of the digital information worldwide. However, after more than two decades of intense research, the understanding of the fundamental physical processes governing the transfer of angular momentum necessary for magnetic switching, is still lacking, partially hampered by the appropriate experimental tools.
