Frank constants calculation method for erbium-based liquid crystal

Abstract

Abstract The orienting effect of a magnetic field on an erbium-based liquid crystal complex was studied by a capacitance method. The dependence of the effective dielectric permittivities of the complex on the magnetic field is obtained. A theoretical approach and a numerical method for determining the Frank elastic constants are proposed based on the experimental dependence of the effective values of the permittivity on various magnetic fields.
