abstract: |
The field assisted sintering offers the unique possibility to consolidate materials
while maintaining nanostructures. This method can be used to tailor grain sizes in
sintered permanent bulk magnets. Since the physical properties of the bulk material
changes, these changes have to be originated by variations of the electronic structure.
In the case of iron rich magnetic materials, Moessbauer spectroscopy is an ideal tool
to detect such variations. It is demonstrated that for nanostructured iron oxide bulk
materials, the hyperfine interactions change due to the small size of grains below
80 nm.
