Abstract

A detailed analysis of approximately fifty iron-57 Mössbauer spectra of R₂Fe₁₄B and R₂Fe₁₄C, obtained as a function of rare-earth and temperature, reveals that the iron 8j₂ site has the largest hyperfine field of the six crystallographically distinct iron sites present in these compounds. This experimental result does not agree with a recent calculation of the hyperfine fields in R₂Fe₁₄B which indicates that the 16k₂ site has the largest hyperfine field. The inconsistency of this calculation with the experimentally measured hyperfine fields leads to the conclusion that the calculated hyperfine fields must be accepted with caution.
