| dc.description.abstract | The grain boundary phase/material found to be
present in two-phase mechanically alloyed nanocomposites
of Sm2Fel7N3/Fe and NdzFe14B/Fe was characterized
using Mossbauer spectroscopy and magnetization
measurements. The fraction of iron in this third component
is typically 10-15% in Sm*Fel?Ns/Fe and 4-5% in
Nd*Fe14B/Fe nanocomposites. The influence of the grain
size of the nanocomposite and the grain boundary material
on the susceptibility was studied and the results are
discussed in terms of the model of Wang and Mills. | en |
