摘要：

The influence of Fe3O4 nanoparticles on dielectric properties of planar oriented liquid crystal were studied at the frequency range10-(1) - 10(6) Hz and in temperature interval of 292 - 345 K. It was shown that the dielectric spectrum of doped liquid crystal can be divided into two areas. Parameters obtained from the dielectric spectrum for frequencies lower than 10 Hz characterize near electrode processes, and parameters obtained for frequencies more than 10 Hz characterize the bulk properties of the sample. The relaxation time and near-electrode area thickness have been estimated. It was experimentally shown that magnetic nanoparticles change the near-electrode area parameters.
