Abstract

We have investigated electric-field induced magnetic phase transition between the skyrmion lattice and the helix in the multiferroic Cu2OSeO3 by means of small-angle soft x-ray scattering at the Cu L3 absorption edge. By application of electric fields, the skyrmion lattice transforms into helices with distinct modulation vectors depending on the sign of the electric field. In particular, the helix realized under the positive electric field never appears unless the electric field is applied.
