Artykuł
Dielectric dispersion studies in the frequency range between 220 Hz and 1 MHz have been performed on pentakis(imidazolium) undecachlorodibismuthate(III), (C3N2H5)5Bi2Cl11, single crystals. The measurements have been made over the temperature range between 300 and 140 K. It is found that the dielectric dispersion, observed along the b-axis of the monoclinic symmetry (P 21/c), is monodispersive between 166.5 and 168 K, and polydispersive in the close vicinity of Tc = 166 K, for T<Tc + 0.2 K. The observed dielectric dispersion is analysed using a single relaxation mode of the Debye type. Over the paraelectric phase the process of the dielectric critical slowing down is observed. This is characteristic of the order–disorder ferroelectric phase transition.
