Description

An investigation of the 57Fe Moessbauer spectra of the (Sm1-xNdx)2Fe17 and (Sm1-xNdx)2Fe17Ny (x=0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 2<y<3) compounds at room temperature has been reported. The easy axis is found to be in the basal plane for (Sm1-xNdx)2Fe17 and along the c-axis for the whole nitride series (Sm1-xNdx)2Fe17Ny (x≤0.5) from the study of the hyperfine field and quadrupole interactions. The hyperfine field of the (Sm1-xNdx)2Fe17 compounds decreases when the neodymium content increases. The introduction of nitrogen results in a large increase of hyperfine field and isomer shift (f- and h-site). The hyperfine field in (Sm1-xNdx)2Fe17Ny changes very little as x changes from 0.0 to 0.5. (orig.)
