Eigenmode following for direct entropy calculation and characterization of magnetic systems
Stephan von Malottki, Moritz A. Goerzen, Hendrik Schrautzer +2
We present an eigenmode following method (EMF) that has been developed for the numerical scanning of the potential energy surface and the direct calculation of entropy and pre-expo…

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…

Enhanced skyrmion stability due to exchange frustration
S. von Malottki, B. Dupé, P. F. Bessarab +2
Skyrmions are localized, topologically non-trivial spin structures which have raised high hopes for future spintronic applications. A key issue is skyrmion stability with respect t…
