Structural and magnetotransport properties of discontinuous Co/SiO2 multilayers

Results of structural, magnetic and transport properties of magnetic Co/SiO2 granular multilayers, consisting of successive planes of nanosized cobalt clusters embedded in SiO2 and produced by sequential deposition, are presented. Microscopy shows that samples can be composed of a periodical array of Co nanoparticles. Relationships between the nanostructure and magnetotransport properties are discussed.
