The magnetization of relaxed structural models of amorphous Fe-Zr-H alloys is self-consistently computed within the framework of the itinerant-electron theory. A good agreement of the theory with experimental data is found and the effect of hydrogenation is shown to increase drastically the magnetization for Fe-rich concentrations, mainly as a consequence of the underlying volume expansion.
