WebMar 1, 2015 · The measurements using an alternate electric field of 1 kHz proved that the Freedericksz transition threshold decreased from 0.79 Vrms to 0.54 Vrms. Under similar conditions, in [15] , the authors studied a mixture of BaTiO 3 in 6CHBT liquid crystal and found an increase of the threshold voltage for Freedericksz transition from 0.7 Vrms to … WebOct 31, 2024 · 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 ... WebMay 26, 2010 · Within the continuum theory we study the magnetic segregation effects in ferronematics, i.e., suspensions of monodomain magnetic particles in nematic liquid crystals. Orientational and concentrational distributions in a ferronematic layer are obtained as functions of a magnetic field strength for different values of material parameters. … physiosuit co2 filter
