Abstract

Neutron diffraction has been used to study a series of Y₂Fe₁₄₋ₓAlₓB solid solutions with x=0.65, 0.92, 1.30, 1.53, and 1.93. Aluminum atoms are found to occupy the j₂ and c sites. the Al site affinity appears to be determined by the steric effect (j₂) or crystal environment (c). The c lattice parameter increases as the aluminum content x increases, while the a lattice parameter decreases as the aluminum content x increases. The unit cell volume increases as the aluminum content x increases, at a rate around 3 ų per Al atom per formula unit, much lower than observed in the Al substituted 2:17 compound. the average Fe site moment Decreases as the aluminum content x increases due to the reduction of the Fe content.
