Here we report results of the study of bent-core (BC) cybotactic nematic LC by dielectric spectroscopy and electro-optic measurements. In the absence of electric ﬁeld, this material is uniaxial and exhibits only one relaxation process corresponding to the ﬂuctuations of the polar clusters. The application of the external electric ﬁeld induces biaxialityandthesecondrelaxationprocessappearsinthedielectricspectra.Thisisassigned to the collective mode. Possible models for cluster transformation under electric ﬁeld are discussed.
