The dielectric properties of a paramagnetic terbium-containing liquid crystal have been studied. The magnitude and the sign of the dielectric of the liquid crystalline complex have been determined. The relaxation processes (modes) characterizing the dispersion of the principal values of the sample’s dielectric permittivity has been studied. The relaxation times, activation energy and the dipole moment of the complex could be evaluated.

Keywords: lanthanidomesogens, dielectric permittivity, dielectric anisotropy.
