Abstract (EN): The modulation wave vector q=delta(T)c* of deuterated betaine calcium chloride dihydrate (D-BCCD) was measured as a function of the temperature for certain dc electric fields, using elastic neutron scattering. The results obtained are compared with the behavior of the dielectric constant of electric-field-biased D-BCCD. The temperature range of stability of the polar phases with delta=2/7, 4/15, 2/9, 2/11 increases with a dc electric field along b. The results are discussed qualitatively, in terms of Landau theory.
