  3. 22. Some aspects of the slow motion problem in the NMR-relaxation theory : a theoretical study of high spin systems

    Författare :Per-Olof Westlund; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A theory of nuclear spin relaxation in paramagnetic complexes, allowing for the electron spin relaxation to be in the slow motion regime, is presented. The lattice i3 described in terms of the electron Zeeman interaction, a zero field splitting (ZFS) and a Markov operator for the relevant classical degrees of freedom. LÄS MER

  4. 23. Spin transport in normal and superconducting nanowires

    Författare :Ninos Poli; Vladislav Korenivski; Mark Johnson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : Todays conventional electronic devices are based on electron charge transport in semiconductor channels. Spintronics is a rapidly emerging technology, which exploits the spin degree of freedom as well as the charge of the electrons. LÄS MER
