    Atomistic spin simulations of electric-field-assisted nucleation and annihilation of magnetic skyrmions in Pd/Fe/Ir(111) 
    Goerzen, Moritz Alexander; von Malottki, Stephan; Kwiatkowski, Grzegorz; Bessarab, Pavel; Heinze, Stefan (American Physical Society (APS), 2022-06-27)
    We provide a theoretical background for electric-field-assisted thermally activated writing and deleting of magnetic skyrmions in ultrathin transition-metal films. We apply an atomistic spin model, which includes the exchange interaction, the ...

    Duplication, Collapse, and Escape of Magnetic Skyrmions Revealed Using a Systematic Saddle Point Search Method 
    Müller, Gideon Philipp; Bessarab, Pavel; Vlasov, Sergei M.; Lux, Fabian; Kiselev, Nikolai S.; Blügel, Stefan; Uzdin, Valery M.; Jónsson, Hannes (American Physical Society (APS), 2018-11-06)
    Various transitions that a magnetic Skyrmion can undergo are found in calculations using a method for climbing up the energy surface and converging onto first order saddle points. In addition to collapse and escape through a boundary, the method ...

    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 ...
