METHOD FOR PRODUCING AN ELEMENT, INCLUDING A MULTIPLICITY OF NANOCYLINDERS ON A SUBSTRATE, AND USE THEREOF

摘要

A method for producing an element including a substrate having a plurality of nanocylinders deposited thereon includes providing the substrate. The substrate is covered with a nanoporous Al₂O₃ membrane so as to provide a covered substrate. The covered substrate is alternately vapor-deposited, at a vapor-deposition temperatures from 250° C. to 400° C., with atoms of a magnetic element and atoms of a non-magnetic element so as to provide the plurality of nanocylinders. Each nanocylinder includes at least four superposed layers including, alternatively, the atoms of the magnetic element and the atoms of the non-magnetic element. The nanoporous Al₂O₃ membrane is then removed so that the nanocylinders remain on the substrate.
