Insertion of light elements such as H, C or N in the R2Fe17 series (R=rare-earth) has been found to improve some magnetic properties of most ferromagnetic compounds of the series, thus becoming prospective candidates for metal-bonded permanent magnets. For instance spectacular increases of Tc and Ms have been observed upon interstitial insertion. Among the R2 Fe17Hx series we focused on the Gd compound and we report on high field magnetization measurements that have been carried out on the Gd2Fe17Hx system (x=0, 3 and 5). The measurements have been performed up to 200 kOe in continuous field. We present the isothermal magnetization curves measured between 2 K and 300 K on powder samples embedded in a resin then aligned under a magnetic field of about 10 kOe in order to get oriented samples. The magnetic anisotropy constants K1 and K 2 have been determined taking into account the angular distribution of the grain axes. Their thermal variation as a function of hydrogen concentration is presented. Finally, the observed effect of hydrogen on the iron sublattice anisotropy is compared to that observed in other systems such as R2Fe14BHx
