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…
Stability and magnetic properties of Fe double-layers on Ir (111)
Melanie Dupé, Stefan Heinze, Jairo Sinova +1
We investigate the interplay between the structural reconstruction and the magnetic properties of Fe doublelayers on Ir (111)-substrate using first-principles calculations based on…
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…
Trochoidal motion and pair generation in skyrmion and antiskyrmion dynamics under spin-orbit torques
Ulrike Ritzmann, Stephan von Malottki, Joo-Von Kim +3
Skyrmions and antiskyrmions in magnetic ultrathin films are characterised by a topological charge describing how the spins wind around their core. This topology governs their respo…
Domain walls and Dzyaloshinskii-Moriya interaction in epitaxial Co/Ir(111) and Pt/Co/Ir(111)
Marco Perini, Sebastian Meyer, Bertrand Dupé +5
We use spin-polarized scanning tunneling microscopy and density functional theory (DFT) to study domain walls (DWs) and the Dzyaloshinskii-Moriya interaction (DMI) in epitaxial fil…
