  The lack of inversion symmetry in the crystal lattice of magnetic materials
gives rise to complex non-collinear spin orders through interactions of
relativistic nature, resulting in interesting physical phenomena, such as
emergent electromagnetism. Studies of cubic chiral magnets revealed a universal
magnetic phase diagram, composed of helical spiral, conical spiral and skyrmion
crystal phases. Here, we report a remarkable deviation from this universal
behavior. By combining neutron diffraction with magnetization measurements we
observe a new multi-domain state in Cu2OSeO3. Just below the upper critical
field at which the conical spiral state disappears, the spiral wave vector
rotates away from the magnetic field direction. This transition gives rise to
large magnetic fluctuations. We clarify physical origin of the new state and
discuss its multiferroic properties.
