, in which it can be seen that the change in a variety of materials properties appears to be significantly greater in going from conventional crystalline material to nanocrystalline material than in going from crystalline to glassy solid, changes that are generally less than 10 percent. Very few property measurements have been made on nanophase materials to date, and the full impact of their ultrafine microstructures on their properties will only be elucidated by further research in this new area of materials synthesis.

The detailed magnetic properties of these nanophase Er samples are thus strongly affected by the nanometer scale of their grains and consequently the large volume fraction of grain boundaries. How these properties depend on the grain size, the fraction and location of atoms in grain boundary sites, and the possible formation of Er-oxygen compounds at these interfaces during synthesis, however, remains to be elucidated.
