The 57 Fe Mössbauer spectrum of the Nd 2 Fe 14 B compound at 83 K is analyzed with eighteen Zeeman sextuplets by taking into account of the splittings of the six Fe sites (Fe c , Fe c , Fe j1 , Fe j2 , Fe k1 , and Fe k2 ) into 2, 2, 3, 3, 4, and 4 magnetically inequivalent sub‐sites. The spectrum at 295 K is analyzed with six Zeeman sextuplets. The electric quadrupole splittings at each Fe site are calculated on the basis of a point charge model with different electric charges for Fe and B. When the charges of Nd, Fe, and B are 3 e , 2 e and zero ( e > 0), the calculated results coincide with those obtained by fitting the Mössbauer spectra measured at 83 and 295 K.
