Fe substitution for Co leads to the increase of the Curie temperatures of both HoCo4-xFexAl and
YCo4-xFexAl and of the spin-reorientation temperature of HoCo4-xFexAl. In contrary, the anisotropy field
of YCo4-xFexAl decreases quickly with increasing Fe content. The results are explained in terms of the
individual site anisotropy model. ?? 1995.
