Gorobets O. Spatial self-organization in a solid state under the influence of a magnetic field and electrochemical reactions

Object: solid bodies under influence of magnetic fields and electrochemical reactions at their surface. The purpose: solving of the problem relative to revealing peculiarities of the combined influence of a magnetic field and electrochemical reactions on structure and physical properties of the solid bodies under conditions of spatial self-organization. Methods: raster electron microscopy, optical microscopes. Results: it was done the following under the influence of a constant magnetic field and electrochemical reactions at the solid state surface - it was experimentally revealed spatially quasiperiodic distribution of electric potential in conducting uniform solid bodies by means of observation of formation of mesoscale vortex structure in the vicinity of an interface with an electrolyte; dependence of the size and number of the mesoscale spatial periods of the vortex structure on the distribution of dielectric and conducting regions at the surface of such a cylinde r; formation and characteristics of the self-organized quasiperiodic microscale structure of the corroded samples; model of spatially periodic mesoscale distribution of electric potential in a uniform conducting solid state sample; it was explained that formation of periodical microscale structure of the corroded ferromagnet is the result of distribution of its magnetostatic fields; the new type of exact 3D solutions of nonlinear Landau-Lifshits equations is obtained for a wide range of solid bodies. The field of application: physics of the solid state, magnetism, synergetics
