Self-assembly of magnetic multilayer polymer films on the base of polyelectrolytes and magnetic suspensions

Possibility of the manufacturing magnetic ultra-thin multilayer films with exactly controlled thickness of separated polymer layers was considered. Magnetic multilayer nanocomposites based on polyelectrolytes have been prepared by alternate layer-by-layer assembly method. They were investigated by optical, magneto-optical and electron microscopy and electron diffraction methods. It is shown that the planar surface charge sign influences on the magnetic layer density.
