Freedericksz Transitions in Twisted Ferronematics Subjected to Magnetic and Laser Field

Abstract

<jats:p>The influence of the anchoring forces on the Freedericksz transition in twisted ferronematics simultaneously subjected to magnetic and laser fields is studied in this work. Using the elastic continuum theory and Gouchen model for molecular anchoring on the cell support plates, the critical field and the saturation field were calculated as a function of the laser intensity and anchoring strength for two types of ferronematics based on 5CB and CCN-37 liquid crystals.</jats:p>

Nematic Liquid Crystals

“…The dielectric data were analyzed in terms of dynamics properties and the "quasi-critical" approach. Cirtoaje et al [3] report theoretical considerations of the Freedericksz transition in two ferronematics based on 5CB and CCN-37 liquid crystals. The elastic continuum theory and Gouchen model were employed to demonstrate the significant influence of the anchoring forces and laser beam on the critical field and saturation field in ferronematics.…”
