    Comment on “Path to collapse for an isolated Néel skyrmion” 
    Bessarab, Pavel (American Physical Society (APS), 2017-04-24)
    Rohart et al. [Phys. Rev. B 93, 214412 (2016)] recently reported calculations indicating two mechanisms for the annihilation of a skyrmion in a Co monolayer on Pt(111). The path calculations were based on a method presented in the Supplemental Material ...

    Dynamic impurities in two-dimensional topological-insulator edge states 
    Wozny, Simon; Leijnse, Martin; Erlingsson, Sigurdur I. (2021-11-15)
    Helical edge states of two-dimensional topological insulators show a gap in the density of states (DOS) and suppressed conductance in the presence of ordered magnetic impurities. Here we will consider the dynamical effects on the DOS and transmission ...

    Energy surface and lifetime of magnetic skyrmions 
    Uzdin, V.M.; Potkina, M.N.; Lobanov, I.S.; Bessarab, Pavel; Jónsson, Hannes (Elsevier BV, 2017-11)
    The stability of skyrmions in various environments is estimated by analyzing the multidimensional surface describing the energy of the system as a function of the directions of the magnetic moments in the system. The energy is given by a Heisenberg-like ...

    Induced uniaxial magnetic anisotropy in polycrystalline, single crystal and superlattices of permalloy 
    Kateb, Movaffaq (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2019-12-12)
    Permalloy Ni80Fe20 at. % (Py) is a well-known ferromagnet utilized in anisotropic magnetoresistance and planar Hall effect sensors as well as magnetic read heads in magnetic memories. These applications rely on the uniaxial magnetic anisotropy in ...

    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 ...

    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 ...
