Coupling of the triple-Q state to the atomic lattice by anisotropic symmetric exchange
Felix Nickel, André Kubetzka, Soumyajyoti Haldar +3
We identify the triple-Q (3Q) state as magnetic ground state in Pd/Mn and Rh/Mn bilayers on Re(0001) using spin-polarized scanning tunneling microscopy and density functional theor…
Evidence for a conical spin spiral state in the Mn triple-layer on W(001): spin-polarized scanning tunneling microscopy and first-principles calculations
Paula M. Weber, Tim Drevelow, Jing Qi +2
The spin structure of a Mn triple layer grown pseudomorphically on surfaces is studied using spin-polarized scanning tunneling microscopy (SP-STM) and density functional theory (DF…
Lifetime of coexisting sub-10 nm zero-field skyrmions and antiskyrmions
Moritz A. Goerzen, Stephan von Malottki, Sebastian Meyer +2
Magnetic skyrmions have raised high hopes for future spintronic devices. For many applications it would be of great advantage to have more than one metastable particle-like texture…
Tuning the magnetic interactions in van der Waals FeGeTe heterostructures: A comparative study of \textit{ab initio} methods
Dongzhe Li, Soumyajyoti Haldar, Tim Drevelow +1
We investigate the impact of mechanical strain, stacking order, and external electric fields on the magnetic interactions of a two-dimensional (2D) van der Waals (vdW) heterostruct…
Strain-Driven Zero-Field Near-10 nm Skyrmions in Two-Dimensional van der Waals Heterostructures
Dongzhe Li, Soumyajyoti Haldar, Stefan Heinze
Magnetic skyrmions localized chiral spin structures show great promise for spintronic applications. The recent discovery of two-dimensional (2D) magnetic materials opened n…
Nano-scale collinear multi-Q states driven by higher-order interactions
Mara Gutzeit, André Kubetzka, Soumyajyoti Haldar +4
Complex magnetic order arises due to the competition of different interactions between the magnetic moments. Recently, there has been an increased interest in such states not only…
