Calculation of the Membrane Thickness of Magnetite Nanoparticles on the Surface of the Transparent Conductive Electrode in the Electric Field

摘要

We observe and study the reflection and interference in the two-layer thin film composed of a conductiveudlayer of ITO and dispersed particles of magnetic fluid (magnetite). In an electric field the equivalentudthickness of the membrane is increased by varying the thickness of the second layer. At a certain value ofudthe electric field the layer becomes unstable, its thickness varies periodically, autowave process leading toudthe characteristic active centers (pacemakers), spiral waves (reverberators) was observed.
