Resumo
Anomalous x-ray synchrotron diffraction was used to determine the crystallographic parameters of PrFeCoBbased
magnetic alloys. The effect of cobalt concentration on the crystallographic parameters of the magnetically
hard Pr2Fe14−xCoxB phase was studied. The results indicate that addition of cobalt has a marked effect on crystal
structure. Variation of the c parameter decreased twice as much as the a parameter with increase in Co content.
The positions of inequivalent atoms of the magnetically hard matrix phase ϕ in the Pr-based alloys were
determined using Rietveld refinement. This permitted determination of the relative distance of each
inequivalent atom from its nearest neighbors. Cobalt occupied the 16k2 site and Fe had a tendency to occupy
the 8j2 sites located between the Kagomé layers.
