- Three kinds of commercial Nd-Fe-B based materials were compared using $\text{}^{57}Fe$ Mössbauer spectroscopy and X-ray analysis: near the $Nd_2Fe_{14}B$ stoichiometry and with both lowered and raised Nd content. Magnetically hard $Nd_2Fe_{14}B$ is present in all three materials. In the Nd-low material it is accompanied with the magnetically soft $Fe_3B$ phase, building the nanocomposite structure. In the Nd-rich sample the overstoichiometric Nd atoms seem to build separate phase of Fe-Nd solid solution. None of the materials contain significant content of phases degrading magnetic characteristics, with except of minor $Nd_{1.1}Fe_4B_4$ one.
