Dielectric properties of nematic liquid crystals with Fe₃O₄ nanoparticles in direct magnetic field

摘要

Researched within the frequency range 10⁻¹–10⁶ Hz were dielectric propertiesudof pure 6CHBT liquid crystals and 6CHBT ones with the impurity of Fe₃O₄ nanoparticlesudthat have the mean diameter 5 nm and weight concentration 10⁻⁴ %. The study wasudperformed without and under the influence of direct magnetic field with the inductionud0.45 and 0.60 T. It has been shown that the magnetic field influences on the parametersudof the near-electrode area of liquid crystal. In the case of liquid crystal with magneticudnanoparticles, the parameter changes caused by the magnetic field depend on theudinduction value.
