Phase autowaves in the near-electrode layer in the electrochemical cell with a magnetic fluid

A change in color of the thin pellicle when light is reflected from the surface of the magnetic fluid at the interface with the transparent electrode in the electric field was observed. The formation of variable thickness near-electrode layer leads to a change in the spectrum of the reflected light depending on the applied voltage. Autowaves, that were observed in the layer are a unique object for the study of self-organization process. •A change of the thin pellicle color in the electric field was observed.•Formation of layer leads to a change in the spectrum of reflected light.•Autowaves with the typical leading centers and spiral waves were observed.
