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…
Role of Dzyaloshinskii-Moriya interaction for magnetism in transition-metal chains at Pt step-edges
Benedikt Schweflinghaus, Bernd Zimmermann, Marcus Heide +2
We explore the emergence of chiral magnetism in one-dimensional monatomic Mn, Fe, and Co chains deposited at the Pt(664) step-edge carrying out an ab-initio study based on density…
