Abstract The amorphous Fe_(90-x)V_xZr_(10) alloy after electrolytic hydrogenation pro-cedure was studied by means of Mossbauer effect, magnetic measuement, X-ray dif-fraction and second ion mass spectroscopy (SIMS) techniques. The experimental re-sults show that the magnetic properties of amorphous Fe_(90-x)V_xZr_(10) alloy are highlysensitive to presence of hydrogen. The isomer shift (IS) has a small positive changeand the magnetic properties transfer from paramagnetic to ferromagnetic state byhydrogenation. The effect of hydrogen absorption is also to raise Fe magnetic mo-ment and Curie temperature T_C from 257 to 384 K. Finally, the considerable in-crease of magnetic properties of amorphous Fe_(90-x)V_xZr_(10) alloy by hydrogenation is at-tributable to the change of hydridization effect between outer electrons of Zr atomsand 3d-electrons of Fe atoms. It may be concluded that the hydrogen atoms is loca-lized around Zr atoms when hydrogen atoms enter inside of alloy.
