Cobalt nanoparticles deposited and embedded in AIN: Magnetic, magneto-optical, and morphological properties

View publication


The study of cobalt nanoparticles deposited on 50 Å AlN/c-sapphire substrates and embedded in an AlN matric was presented. The dependence of the properties of Co nanoclusters deposited on AlN were also studied. The properties of as grown and AlN embedded Co nanoclusters were directly compared. It was shown hat the AlN matrix has a strong impact on their magnetic and magneto-optical properties.
