Here we report additional insights in the dynamics of this remarkable phenomenon. In particular, we have elucidated the role and the influence of the dc and ac electric field on 111 oriented BaTiO3 single-crystal in the rhombohedral phase. It is shown that the effect of the dielectric permittivity increase is strongly connected with the probing ac voltage while it does not depend on the dc electric field value. In addition, the frequency dependence has been studied in details within the 10 Hz to 1MHz range and for various amplitudes of the ac field.
