Structure and Magnetism of well-defined cobalt nanoparticles embedded in a niobium matrix

, 2000
Our recent studies on Co-clusters embedded in various matrices reveal that the co-deposition technique (simultaneous deposition of two beams : one for the pre-formed clusters and one for the matrix atoms) is a powerful tool to prepare magnetic ...
