abstract = "Among novel magnetic intermetallics based on rare earth-transition compounds, the Nd2Fe14B/alpha-Fe isotropic nanocomposites have been obtained by recrystallization from an amorphous phase, prepared by melt spinning. For variable 5 wt.% Fe and 10 wt.% Fe contents we recorded transmission Fe-57 Mossbauer spectra at the room temperature, hardened of the alpha-Fe phase by exchange interactions. The spectra have been analyzed in terms of ten Zeeman sextets and one paramagnetic doublet related to the Nd1.1Fe4B4 phase. One sextet corresponds to the alpha-Fe phase, whereas others are attributed to six non-equivalent Fe sites in the Nd2Fe14B structure, namely 16k(1), 16k(2), 8j(1), 8j(2), 4c, and 4e. The three remaining sextets belong to the Fe3B structure with three inequivalent Fe sites Fe-I(8g), Fe-II(8g) and Fe-III(8g). All relevant parameters for both nanocomposites: the magnetic hyperfine field, the isomer shift and the quadrupole splitting are determined for each of these sites.",
