Abstract
The structuralization of magnetic particles after illumination was experimentally observed in two types of a magnetic fluid based on mineral oil with the magnetite particles covered by monolayer surfactant and kerosene-based magnetic fluid sterically stabilized by a double layer consisting of oleic acid and dodecylbenzensulphonic acid (DBS). This contribution presents a detailed theoretical description of the thermodiffusion process in magnetic fluids, simulation of the structuralization in magnetic fluid with a negative Soret constant, and confirmaton of the negative value of this constant for a kerosene-based magnetic fluid.
