    First-principles prediction of sub-10-nm skyrmions in Pd/Fe bilayers on Rh(111) 
    Haldar, Soumyajyoti; von Malottki, Stephan; Meyer, Sebastian; Bessarab, Pavel; Heinze, Stefan (American Physical Society (APS), 2018-08-27)
    We show that stable skyrmions with diameters of a few nanometers can emerge in atomic Pd/Fe bilayers on the Rh(111) surface. Based on density functional theory we calculate the exchange and the Dzyaloshinskii-Moriya interaction as well as the ...

    Prediction of stable nanoscale skyrmions in monolayer Fe5GeTe2 
    Li, Dongzhe; Haldar, Soumyajyoti; Kollwitz, Leo; Schrautzer, Hendrik; Goerzen, Moritz A.; Heinze, Stefan (American Physical Society (APS), 2024-06-10)
    Using first-principles calculations and atomistic spin simulations, we predict stable isolated skyrmions with a diameter below 10 nm in a monolayer of the two-dimensional van der Waals ferromagnet Fe5⁢GeTe2, a material of significant experimental ...

    Skyrmion lifetime in ultrathin films 
    von Malottki, Stephan; Haldar, Soumyajyoti; Delin, Anna; Heinze, Stefan; Bessarab, Pavel (American Physical Society (APS), 2019-02-26)
    We show that thermal stability of skyrmions due to entropic effects can be strongly affected by external control parameters such as magnetic field and interface composition. The lifetimes of isolated skyrmions in atomic Pd/Fe bilayers on Ir(111) and ...
