Abstract
After reporting on the general features of 57Fe Mössbauer spectrometry, we illustrate with some examples to show how this technique brings relevant information first in materials science (chemistry, physics, geology, archeology, …) and then to confined systems (0D, 1D, 2D and 3D nanostructures). Indeed, its local probe behavior allows in the case Fe-containing nanostructures to give evidence for chemical heterogeneities, to discriminate structural and magnetic surface and volume effects in some nanoparticles and hollow nanoparticles, to establish the role of grain boundaries or interfaces in magnetic nano-architectures and to follow both static and dynamic magnetic phenomena.
