Descrição: The magnetization of the pseudo-binary intermetallic compounds <math>(Dy_{x}Y_{l-x})Fe_2\,\!</math> and <math>(Er_{x}Y_{1-x})Fe_2\,\!</math> was studied in high magnetic fields <math>(up\,\!</math> to <math> 20 \,\!</math> <math>T)\,\!</math>. The saturation magnetization shows a minimum as a function of concentration, due to the anti parallel coupling of the <math>R\,\!</math> and <math>Fe\,\!</math> moments. From the magnetization curve in the high field region we derived the spontaneous magnetization and high field susceptibility, as a function of concentration. The susceptibilities, coercive fields and the anisotropy terms show maxima in the <math>20 - 40%\,\!</math> concentration range.
