Characterization of Zn Doped Insulating Magnetic Skyrmion Material Cu<sub>2</sub>OSeO<sub>3</sub>

ORAL

Abstract

Cu2OSeO3 has recently received significant attention as the only known insulating skyrmion material, offering interesting insights into the exchange interactions within magnetic materials. Magnetization studies have suggested that Zn substitutions on the Cu site can split the skyrmion phase into two separate temperature/field regions. However, the skyrmion phase splitting in (Cu1-xZnx)2OSeO3 has not been directly confirmed with structural measurements, and the mechanism for this split is unclear. In this talk, I discuss our work to synthesize and characterize (Cu0.9Zn0.1)2OSeO3, results from our magnetization and small angle neutron scattering (SANS) measurements, and their ramifications.
