Abstract

The Mössbauer spectra of Y₂Fe₁₄B have been measured from 85 to 296 K. Analysis of the spectra indicates that the near-neighbor rare-earth atoms directly influence the orientation of the principal axis of the electric field gradient. The hyperfine parameters are very similar to those of Nd₂Fe₁₄B, but the internal fields are somewhat smaller at room temperature in the yttrium compound. The Mösssbauer spectra of Y₂(Fe_1-xAl_x) ₁₄B, where x equals 0.00, 0.02, 0.04, 0.06, and 0.08, have been measured at 85 K. The average internal hyperfine field in these compounds decreases linearly with increasing aluminum content.
