Abstract
Abstract We report the phase states in dodecyltrimethyl ammonium bromide/water (DDTMABr–H2O) lyotropic liquid crystalline system. The temperature-concentration phase diagram of this system has been determined. Isotropic micellar L1 phase, nematic-calamitic NC and hexagonal E mesophases have been observed in DDTMABr/H2O system. Dynamics of transformations of magnetically induced textures in NC and E mesophases has been investigated. Temperature and concentration dependences of the refractive index in the L1 phase, NC and E mesophases have been determined. The appearance of the magnetically induced aligned textures of NC mesophase and changes of the optical birefringence vs. time have been investigated.
