Query: Electric-field control of the skyrmion lattice in Cu2OSeO3   Small-angle neutron scattering has been employed to study the influence of
applied electric (E-) fields on the skyrmion lattice in the chiral lattice
magnetoelectric Cu2OSeO3. In an experimental geometry with the E-field parallel
to the [111] axis, and the magnetic field parallel to the [1-10] axis, we
demonstrate that the effect of applying an E-field is to controllably rotate
the skyrmion lattice around the magnetic field axis. Our results are an
important first demonstration for a microscopic coupling between applied
E-fields and the skyrmions in an insulator, and show that the general emergent
properties of skyrmions may be tailored according to the properties of the host
system.
