Abstract

The ferromagnetic and glassy transitions in nanostructured GdAl2 were analyzed using Curie-Weiss analysis. The spin-like glass transitions in nanostructured GdAl2 occurs at a higher temperature than the freezing temperature of amorphous GdAl2 thin films. Curie-Weiss analysis suggests that the paramagnetic-to-ferromagnetic transition was due to the ferromagnetic ordering of small GdAl2 clusters and that the glassy transition was due to the spin-glass-like ordering of a surface/interface phase.
