Descripción
Magnetic nanoparticles have been object of renewed interest in the last years due to their multidisciplinary interest. Series of Rare Earth nanoalloys of TbCu2 have been produced by inert-atmosphere milling. To establish their magnetic character a thorough static and dynamic susceptibility analysis has been accomplished. The magnetic structure retains the bulk structure and there is an increased effect due to a moment canting (Tf ? 20 K) at the surface when the particle size becomes more and more reduced. From a macroscopic point of view, there is a coexistence of antiferromagnetism in the nanoparticle core with the spin glass disorder at the shell.
