    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 ...

    Interplay between size and stability of magnetic skyrmions 
    Varentsova, A.S.; Potkina, Maria; von Malottki, S.; Heinze, S.; Bessarab, Pavel (ITMO University, 2018-06-24)
    The relationship between the size and stability of isolated skyrmions in a magnetic monolayer is analyzed based on minimum energy path calculations and atomistic spin Hamiltonian. It is demonstrated that the energy barrier protecting the skyrmion from ...

    Stability and dynamics of chiral magnetic structures in ferro- and antiferromagnets 
    Potkina, Maria (University of Iceland, School of Engineering and Natural Sciences, Faculty of Physical Sciences, 2022-06-29)
    Reduction of the size of magnetic bits for data storage, transfer and processing of information down to the nanoscale would lay the foundation for large advances in information technology, both in terms of processing speed and energy efficiency. ...
