Material systems for FM-/AFM-coupled skyrmions in Co/Pt-based multilayers
Hongying Jia, Bernd Zimmermann, Markus Hoffmann +3
By means of systematic first-principles calculations based on density functional theory we search for suitable materials that can host antiferromagnetically coupled skyrmions. We c…
Electric dipole moment as descriptor for interfacial Dzyaloshinskii-Moriya interaction
Hongying Jia, Bernd Zimmermann, Gregor Michalicek +2
Chiral magnets are of fundamental interest and have important technological ramifications. The origin of chiral magnets lies in the Dzyaloshinskii-Moriya interaction (DMI), an inte…
Comparison of first-principles methods to extract magnetic parameters in ultra-thin films: Co/Pt(111)
Bernd Zimmermann, Gustav Bihlmayer, Marie Böttcher +6
We compare three distinct computational approaches based on first-principles calculations within density functional theory to explore the magnetic exchange and the Dzyaloshinskii-M…
Dzyaloshinskii-Moriya interaction at disordered interfaces from ab initio theory: robustness against intermixing and tunability through dusting
Bernd Zimmermann, William Legrand, Davide Maccariello +4
The Dzyaloshinskii-Moriya interaction (DMI), which is essential for the stabilization of topologically non-trivial chiral magnetic textures such as skyrmions, is particularly stron…
First-principles investigation of chiral magnetic properties in multilayers: Rh/Co/Pt and Pd/Co/Pt
Hongying Jia, Bernd Zimmermann, Stefan Blügel
The magnetic properties of (111)-oriented Rh/Co/Pt and Pd/Co/Pt multilayers are investigated by first-principles calculations. We focus on the interlayer exchange coupling, and ide…
Spin-orbit torques and spin accumulation in FePt/Pt and Co/Cu thin films from first principles: the role of impurities
Guillaume Géranton, Bernd Zimmermann, Nguyen Hoang Long +4
Using the Boltzmann formalism based on the first principles electronic structure and scattering rates, we investigate the current-induced spin accumulation and spin-orbit torques i…
