Vertical self-organization of epitaxial magnetic nanostructures
Journal of Magnetism and Magnetic Materials 239, (1-3),pp 224-227 Elsevier, (2002)
We report the fabrication of epitaxial nanometer-thick magnetic structures, self-organized on surface reconstructions [Co/Au (111) pillars] and atomic step arrays [Fe/Mo (110) stripes]. Due to their high volume, these structures are remanent at room temperature, whereas conventional self-organized flat systems obtained in the sub-monolayer deposition range are superparamagnetic down to low temperatures.
