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…

Partial Kondo Screening Solves the Mystery of Rare Earth Tetraborides

Soumyaranjan Dash, Sanjeev Kumar

We invoke a new mechanism to account for multiple magnetization plateaus observed in rare-earth tetraborides. Using a combination of hybrid and semiclassical Monte Carlo simulation…
