Topological spin-texture transitions in van der Waals magnets revealed by X-ray Fourier transform holography
Sourav Chowdhury, Soumyaranjan Dash, Michael Schneider +14
Nontrivial topological spin-textures, such as skyrmions, merons, bimerons, and skyrmioniums, are envisioned as robust building blocks for future memory and logic devices. Controlla…

Soft-X-ray momentum microscopy of nonlinear magnon interactions below 100-nm wavelength
Steffen Wittrock, Christopher Klose, Salvatore Perna +10
Magnons are quantised collective excitations of long-range ordered spins. At nanometre wavelengths, exchange interactions increasingly govern their dynamics, giving rise to a large…

A fluctuation-free pathway for a topological magnetic phase transition
Riccardo Battistelli, Lukas Körber, Kai Litzius +27
Topological magnetic textures are particle-like spin configurations stabilized by competing interactions. Their formation is commonly attributed to fluctuation-driven, first-order…
