    The effect of confinement and defects on the thermal stability of skyrmions 
    Uzdin, Valery M.; Potkina, Maria; Lobanov, Igor S.; Bessarab, Pavel; Jónsson, Hannes (Elsevier BV, 2017-09)
    The stability of magnetic skyrmions against thermal fluctuations and external perturbations is investigated within the framework of harmonic transition state theory for magnetic degrees of freedom. The influence of confined geometry and atomic scale ...

    Lifetime of racetrack skyrmions 
    Bessarab, Pavel; Müller, Gideon Philipp; Lobanov, Igor S.; Rybakov, Filipp N.; Kiselev, Nikolai S.; Jónsson, Hannes; Uzdin, Valery M.; Blügel, Stefan; Bergqvist, Lars; Delin, Anna (Springer Nature, 2018-02-21)
    The skyrmion racetrack is a promising concept for future information technology. There, binary bits are carried by nanoscale spin swirls–skyrmions–driven along magnetic strips. Stability of the skyrmions is a critical issue for realising this technology. ...

    Optimal protocol for spin-orbit torque switching of a perpendicular nanomagnet 
    Vlasov, Sergei M.; Kwiatkowski, Grzegorz J.; Lobanov, Igor S.; Uzdin, Valery M.; Bessarab, Pavel (American Physical Society (APS), 2022-04-07)
    It is demonstrated by means of the optimal control theory that the energy cost of the spin-orbit torque induced reversal of a nanomagnet with perpendicular anisotropy can be strongly reduced by proper shaping of both in-plane components of the current ...
