FORMATION OF NANOSTRUCTURES COMPRISING COMPOSITIONALLY MODULATED FERROMAGNETIC LAYERS BY PULSED ECD

摘要

The present invention is related to a method for forming a structure that contains alternating first and second ferromagnetic layers of different material compositions. A substrate containing a supporting matrix with at least one open pore and a conductive base layer is first formed. Electroplating of the substrate is then carried out in an electroplating solution that contains at least one ferromagnetic metal element and one or more additional, different metal elements. A pulsed current with alternating high and low potentials is applied to the conductive base layer of the substrate structure to thereby form alternating ferromagnetic layers of different material compositions in the open pore of the supporting matrix.
