Peculiar domain states of cylindrical BaTiO3 nanorods embedded in SrTiO3 matrix

Original language description

Recent analysis based on the generalized Ginzburg-Landau-Devonshire model and phase-field approach predicts the formation of a simple quadruplet domain configuration in BaTiO3 nanorods embedded in epitaxial SrTiO3 film. This quadruplet configuration canhave three inequivalent variants, differing by the arrangement of the out-of-plane polarization components: uniform orientation in whole nanorod, up-down-up-down? arrangement, or up-up-down-down? arrangement. In the present study, the phase-field simulations are employed to study the temporal evolution of the up-down-up-down? quadruplet domain configuration of 40-nm diameter nanorods under the out-of-plane electric field applied in a finite area within one of the four domains. We have found that this perturbation may lead to the formation of still another, six-domain arrangement, stable at zero-applied field, which is energetically more favorable than the up-down-up-down? arrangement
