Findings demonstrate magnetic field-induced chiral soliton lattices in Cu2OSeO3, highlighting magnetic interactions in application for spintronic devices.
Chiral soliton lattices (CSLs) are anharmonic magnetic structures typically found in uniaxial chiral magnets. In this study, we report the observation of CSL in bulk Cu2OSeO3, a chiral insulator known for its magnetoelectric properties. Using small-angle neutron scattering (SANS) experiments, we demonstrate the formation of CSLs in Cu2OSeO3 at low temperatures, driven by the competition between cubic anisotropy and magnetic field. Our observations of higher harmonics in the SANS signal clearly indicate the anharmonic nature of the spiral. This finding underscores the complex interplay between magnetic interactions in Cu2OSeO3, offering insights for potential applications of CSLs in electric-field-controlled spintronic devices.
