Abstract

We have determined the temperature dependence of the internal hyperfine field, isomer shift, and quadrupole shift at each of the six iron sites in Nd2Fe14B. The hyperfine parameters are consistent with the local iron site environments. The quadrupole and isomer shifts and their temperature dependences support our assignments of the relative ordering of the internal hyperfine fields as j2>k2>c≊k1>j1>c. We obtain a Mössbauer temperature of 390 K for Nd2Fe14B, which compares well with the Debye temperature of 420K for pure iron.
