Abstract The chiral magnetoelectric insulator Cu2OSeO3 hosts a rich and anisotropic magnetic phase diagram that includes helical, conical, field-polarised, tilted conical, and skyrmion lattice phases. Using resonant elastic x-ray scattering (REXS), we uncover a new spiral state confined to the surface of Cu2OSeO3. This surface-confined spiral state (SSS) displays a real-space pitch of ~ 120 nm, which remarkably is twice the length of the incommensurate structures observed to-date in Cu2OSeO3.

Abstract A fundamental question in condensed matter physics concerns how topological electronic states are influenced by many-body correlations, and magnetic Weyl semimetals represent an important material platform to address this problem. However, the magnetic structures realized in these materials are limited, and in particular, no clear example of an undistorted helimagnetic state has been definitively identified.

Overdamped magnons in the field-polarized phase of cubic helimagnet - NPG Asia Materials

By Oleg I. Utesov, Jonathan S. White, Priya R. Baral
| Nature Verified
Abstract Skyrmion-hosting cubic B20 alloys are considered a fruitful platform for various spintronic applications due to their pronounced tunability. However, disorder can limit their usability by pinning skyrmions and scattering magnons. Here, we probe the spin dynamics in the field-polarized phase of the skyrmion host Cr0.82Mn0.18Ge using spin wave small-angle neutron scattering (SWSANS).
