Skyrmion lifetimes in ultrathin films
Stephan von Malottki, Pavel F. Bessarab, Soumyajyoti Haldar +2
We show that thermal stability of magnetic skyrmions can be strongly affected by entropic effects. The lifetimes of isolated skyrmions in atomic Pd/Fe bilayers on Ir(111) and on Rh…
Duplication, collapse and escape of magnetic skyrmions revealed using a systematic saddle point search method
Gideon P. Müller, Pavel F. Bessarab, Sergei M. Vlasov +5
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.…
First-principles prediction of sub-10 nm skyrmions in Pd/Fe bilayers on Rh(111)
Soumyajyoti Haldar, Stephan von Malottki, Sebastian Meyer +2
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 exc…
