Abstract: Iron tracer diffusion was studied in soft-magnetic nanocrystalline Fe90Zr7B3 without any influence of porosity, relaxation, or grain growth. The interfacial diffusion characteristics differ substantially from grain boundaries in metals due to the presence of an intergranular amorphous phase. The reduced diffusivity in thin amorphous layers compared to in the initial amorphous phase indicates the effect of confinement. The indication of a second, fast interfacial diffusion path is found and quantitatively analyzed within the framework of a two interface-type model.

TL;DR: Nanostructured materials and composites as discussed by the authors have attracted enormous interest in basic research as well as in the application oriented engineering sciences or, more recently, even in public media, although - in the historical perspective and even disregarding the obvious coincidence of structure formation on a nanometer scale and basic synthetic chemistry - nanostructures have been around for a very long time.

TL;DR: In this paper, the authors review experimental results and computer simulations on diffusion in metallic glasses and supercooled melts and show that diffusion in these glasses is significantly different from diffusion in crystalline metals and involves thermally activated, highly collective atomic processes.
Soft magnetic nanocrystalline materials
TL;DR: In this article, the microstructure property relationship in soft magnetic nanocrystalline Fe-base materials is surveyed: the basic mechanism is that the magneto-crystalline anisotropy of the small, randomly oriented bcc-Fe grains is averaged out by exchange interaction.

The relaxation dynamics of a simple glass former confined in a pore
TL;DR: In this article, the authors used molecular dynamics computer simulations to investigate the relaxation dynamics of a binary Lennard-Jones liquid confined in a narrow pore, and they found that this dynamics is strongly influenced by the confinement in that time correlation functions are much more stretched than in the bulk.
