Researched within the frequency range 10 -1 -10 6 Hz were dielectric properties of pure 6CHBT liquid crystals and 6CHBT ones with the impurity of Fe 3 O 4 nanoparticles that have the mean diameter 5 nm and weight concentration 10 -4 %. The study was performed without and under the influence of direct magnetic field with the induction 0.45 and 0.60 T. It has been shown that the magnetic field influences on the parameters of the near-electrode area of liquid crystal. In the case of liquid crystal with magnetic nanoparticles, the parameter changes caused by the magnetic field depend on the induction value.
