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…
Noncollinear spin density of an adatom on a magnetic surface
Soumyajyoti Haldar, Stefan Heinze
We show that an individual adatom on a magnetic surface can exhibit a noncollinear spin density. Using density functional theory we study Co and Ir adatoms on a Mn monolayer on the…
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…
