Magneto-optical study of the insulating helimagnet Cu2OSeO3Rolf B. Versteeg1, •Simon Schäfer1, Aisha Aqeel2, Graeme R. Blake2, Thomas T.M. Palstra2, and Paul H.M. van Loosdrecht11II.

The Mott insulator Cu2OSeO3 has recently gained considerable scientific interest owing to the presence of a Skyrmion lattice phase. We report our findings of a comprehensive study of the magneto-optical properties of bulk Cu2OSeO3. The different optical transitions observed in the light polarization rotation spectra allow us to map out the magnetic phase diagram of Cu2OSeO3.
