Study of the electric field control of magnetic domain population in the E-type phase of strained (010) oriented o-LuMnO3 films using spheri
We want to determine electric(E) -field dependence of the magnetic domain population in the E-type phase of multiferroic and strained orthorhombic (o-) LuMnO3 thin film, deposited on (010) oriented o-YAlO3 substrate. In our recent polarized neutron scattering study on IN20 without E-field, we observed the film to display an intrinsic, presumably related to film-strain, domain imbalance in the E-type phase of the o-LuMnO3 film; namely a 60% E1-domain population over 40% E2-domains. . Here we plan to apply an E-field to tune and study the imbalance of the domain population and provide direct proof of magneto-electric coupling in the LuMnO3 film. We will employ the same polarised neutron device CryoPAD set up on IN20 to measure the domain population fraction (E1/E2) under various E-fields. The sample to be measured is a 100 nm thick (010) oriented o-LuMnO3 film.
