Features of the Formation of a Labyrinthine Structure in Thin Layers of Magnetic Fluids in a Constant Electric Field

Abstract

This paper presents the results of studying the features of the formation of structural lattices in thin layers of colloids in an electric field directed perpendicular to the plane of the layer, as well as under the additional influence of a magnetic field. New results were obtained about the dependence of the threshold (critical) value of the electric field strength corresponding to the formation of a labyrinthine structure on the strength of an additionally applied magnetic field, layer thickness, and temperature. The dependences of the formation time of the structure under study on temperature and the strength of the additionally applied magnetic field were characterized. A thermally induced phenomenon of the formation of a labyrinthine structure in a magnetic colloid in the subcritical region of the applied electric field strength under additional exposure to laser radiation was discovered.
