abstract
Some of the new developments on magnetic nanostructures are reviewed. The advances on the synthesis, characterization, and understanding of magnetic dimers, nanoclusters, magnetic nanowires, Heusler alloy thin films, and single molecule magnets, are discussed. Particular emphasis is made on the magnetic properties of: (a) manganese dimer, whose properties is a field of debate and are important to disentangle the multifarious behaviour of the macroscopic samples, (b) manganese nanostructures which show a very rich and complex behaviour, not shown in other transition metal clusters, (c) cobalt magnetic nanowires, which show spin-reorientations as a function of size and microsctructure, (d) Heusler alloys, that are half-metallic present potential applications for spintronics, and magnetic shape memory devices, and (e) single molecule magnets, systems with very high magnetic moments and are homogeneous in macroscopic samples. All these systems are good candidates for technological applications and in particular for the emerging field of spintronics.
