    Local structure in amorphous Smx Co1−x : a combined experimental and theoretical study 
    George, Sebastian; Kádas, Krisztina; Jönsson, Petra E.; Muscas, Giuseppe; Magnus, Fridrik; Eriksson, Olle; Delin, Anna; Andersson, Gabriella (Springer Science and Business Media LLC, 2020-06-12)
    Using a combination of extended X-ray absorption fine structure measurements, stochastic quenching (SQ) calculations and Voronoi tessellation analysis, the local atomic environments in thin films of amorphous SmxCo1−x (x= 0.10, 0.22 and 0.35) are ...

    Microscopic theory for coupled atomistic magnetization and lattice dynamics 
    Fransson, J.; Thonig, D.; Bessarab, Pavel; Bhattacharjee, S.; Hellsvik, J.; Nordström, L. (American Physical Society (APS), 2017-12-13)
    A coupled atomistic spin and lattice dynamics approach is developed which merges the dynamics of these two degrees of freedom into a single set of coupled equations of motion. The underlying microscopic model comprises local exchange interactions between ...

    Optically induced Lifshitz transition in bilayer graphene 
    Iorsh, Ivan; Dini, Kevin Tanguy Elian; Kibis, Oleg; Shelykh, Ivan (American Physical Society (APS), 2017-10-11)
    It is shown theoretically that the renormalization of the electron energy spectrum of bilayer graphene with a strong high-frequency electromagnetic field (dressing field) results in the Lifshitz transition—the abrupt change in the topology of the Fermi ...

    Paleomagnetic Inclination Shallowing in Deep-Sea Sediments 
    Arason, Þórður (Oregon State University, 1991)
    In this thesis anomalous downcore shallowing of paleomagnetic inclinations is interpreted to be caused by sediment compaction. Thus, compaction-induced inclination shallowing may influence tectonic reconstructions that are based on inclinations from ...

    Quantum mechanical tunneling between magnetic states 
    Vlasov, Sergei M. (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2017-12)
    Nanomagnetic systems and transitions between magnetic states are currently an active topic of research. Spintronics is, in particular, a new branch of science and technology where spin degrees of freedom and spin currents are used in an analogous way ...

    Sequential magnetic switching in Fe/MgO(001) superlattices 
    Magnus, Fridrik; Warnatz, T.; Palsson, G. K.; Devishvili, A.; Ukleev, V.; Palisaitis, J.; Persson, P. O. Å.; Hjörvarsson, Björgvin (American Physical Society (APS), 2018-05-24)
    Polarized neutron reflectometry is used to determine the sequence of magnetic switching in interlayer exchange coupled Fe/MgO(001) superlattices in an applied magnetic field. For 19.6 Å thick MgO layers we obtain a 90 ∘ periodic magnetic alignment ...

    Spin relaxation signature of colossal magnetic anisotropy in platinum atomic chains 
    Bergman, Anders; Hellsvik, Johan; Bessarab, Pavel; Delin, Anna (Springer Nature, 2016-11-14)
    Recent experimental data demonstrate emerging magnetic order in platinum atomically thin nanowires. Furthermore, an unusual form of magnetic anisotropy – colossal magnetic anisotropy (CMA) – was earlier predicted to exist in atomically thin platinum ...

    Theory of noncollinear interactions beyond Heisenberg exchange: Applications to bcc Fe 
    Szilva, A.; Thonig, D.; Bessarab, Pavel; Kvashnin, Y. O.; Rodrigues, D. C. M.; Cardias, R.; Pereiro, M.; Nordström, L.; Bergman, A.; Klautau, A. B.; Eriksson, O. (American Physical Society (APS), 2017-10-10)
    We show for a simple noncollinear configuration of the atomistic spins (in particular, where one spin is rotated by a finite angle in a ferromagnetic background) that the pairwise energy variation computed in terms of multiple-scattering formalism ...
