SANS investigation of a new magnetic phase of the chiral skyrmion material Cu2OSeO3

DOI

Studies of cubic chiral magnets reveal a universal magnetic phase diagram, composed of helical spiral, conical spiral as well as skyrmion crystal phase. By combining neutron diffraction with magnetisation measurements we have found a remarkable deviation from this universal behavior. We have observed a new "tilted spiral" conical state in Cu2OSeO3, where the spiral wave vector is tilted away from the magnetic field direction and gives rise to strong diffuse scattering. We now wish to extend previous SANS measurements and investigate the multiferroic properties of this new phase. We also wish to investigate the effect of thermal and magnetic history searching for the co-existence of conical and titled conical phase, as the stabilization of metastable states is an topical issue in chiral magnetism.
