Abstract The room temperature 57Fe Mössbauer spectra for binary iron-based solid solutions Fe1−xOsx, with x in the range 0.01 ≤ x ≤ 0.05, were analyzed in terms of binding energy Eb between two Os atoms in the Fe-Os system. The extrapolated values of Eb for x = 0 were used for computation of enthalpy of solution of osmium in iron. The result was compared with that resulting from the cellular atomic model of alloys by Miedema. The comparison shows that our findings are in qualitative agreement with the Miedema's model predictions.

Increasing Temperature

Mossbauer spectra of YC012B6 and NdCo12B6 doped with enriched 57Fe have been obtained at various temperatures between 4�2 K and room temperature. The spectrum of YC012B6 at 4�2 K indicates that the Co sublattice orders in the crystallographic basal plane. NdCo12B6 orders along or close to the crystallographic c-axis at 4�2 K and undergoes a spin-reorientation with increasing temperature until at ~55 K the magnetisation lies in or near the basal plane.
