Abstract
The dynamical behavior of lyotropic ferronematic liquid crystals of potassium laurate, decanol (or decilamonium chloride), water, and ferrofluid is studied by means of optical techniques, under the influence of magnetic fields. Making use of interferometric measurements, three different processes, with typical characteristic times, were identified. The usual rotational viscosity of lyotropic liquid crystals (∼ 1 p) is obtained associated with the collective behavior of the magnetic particles in the nematic matrix.
