Abstract

Over the last decade there have been significant advances in studying magnetic multilayered structures which, being a new kind of artificial magnetic materials, display a wide array of fascinating properties. These structures consist of thin alternating layers of magnetic and non-magnetic materials with close lattice parameters. Typical examples of magnetic multilayers are Fe/Cr, Co/Cu, and Ni/Ag structures. Magnetic multilayers were found to exhibit numerous intriguing phenomena having no parallel in the bulk properties of the multilayer constituents. It is possible wherewith to influence properties of magnetic multilayers by varying such parameters as material, thickness and morphology of layers, preparation conditions, etc. Thus, one can engineer magnetic multilayers with desirable characteristics. All the above makes magnetic multilayers a challenging object both from a fundamental point of view and for their great potential for technological and engineering applications.
