The light-induced structuralization in magnetic fluids with negative Soret constant

The structuralization of the colloidal particles concentration in illuminated magnetic fluids with negative Soret constant was investigated. A theoretical explanation of the phenomenon, based on the study of the thermodiffusion process in colloidal fluids, was made. The development of the structural...

Summary:The structuralization of the colloidal particles concentration in illuminated magnetic fluids with negative Soret constant was investigated. A theoretical explanation of the phenomenon, based on the study of the thermodiffusion process in colloidal fluids, was made. The development of the structuralization after the intensity of the illumination reaches some critical value was both simulated and observed experimentally.
