| Résumé | Direct evidence of controlling the population of magnetic domains in BiFeO3 thin films through electric field is reported using neutron diffraction. By fabricating BiFeO3 thin films on vicinal SrTiO 3 substrates, we have achieved ferroelectric monodomains as confirmed by piezoresponse force microscopy. The application of an electric field between the bottom SrRuO3 and the top electrode switches the ferroelectric domain state with concomitant changes in magnetic reflections observed with neutron diffraction, indicating changes in the antiferromagnetic domain populations. The observed magnetoelectric switching behavior by neutron diffraction is compared with the electric-field effect on the magneto-optical Kerr effect measurement on patterned pads of exchange coupled Co film deposited on top of the BiFeO3 films. The present result shows possible new directions for the realization of magnetoelectric devices. ©2013 American Physical Society. |
