Electric field effect on the magnetic scattering of GaV4Se8
Magnetic skyrmions in non-centrosymmetric magnets are topologically stable particle-like objects. They are promissing for applications in new type of magnetic memories and logic devices, which criticaly depends on the possibilities for their control by external stimulii. The low-dissipation electric field control of skyrmion lattice state have only been demonstrated in the case of the chiral magnet Cu2OSeO3. Here, we aim to investigate the electric field effect on the modulated magnetic states of a recently discovered multiferroic skyrmion host materials GaV4Se8 using small angle neutron scattering (SANS). Recently, we demonstrated that the ferroelectric domain population in GaV4Se8 can be changed by electric poling. We are going to study if such reconfiguration of the FE domain structure affect the magnetic modulated states. We plan to detect the electric field induced changes in the structural domain population, and we will also seek for the field induced deformation or rotation of the modulated states.
