The amorphous Fe_(90-x)V_xZr_(10) alloy after electolytic hydrogenation procedure was studied bymeans of Mossbauer effect,magnetic measurement.X-ray diffaction and secondary ionmass spectroscopy(SIMS)techniques.The experimental results show that the magneticproperties of amorphous Fe_(90-x)V_xZr_(10) alloy are highly sensitive to the presence of hydrogen.The isomer shift(IS)has a small positive change and the magnetic properties transfer fromparamagnetic to ferromagnetic State by hydrogenation,and the effect of hydrogen absorptionis to raise Fe magnetic moment(from the increase of saturation maguetization)and Curietemperature T_c from 257 to 384 K.Finally.the considerable increase of magnetic properttesof amorphous Fe_(90-x)V_xZr_(10) alloy by hydrogenation is attributable to the change ofhybridization effect between outer electrons of Zr atoms and 3d electrons of Fe atoms.Fromthe results of SIMS experiment,it is concluded that the hydrogen atoms is localized aroundZr atoms wheh hydrogen atoms enter into the allor.
The amorphous results show that the magnetic properties of amorphous Fe_ (90-x) V_xZr_ (10) alloy after electolytic hydrogenation procedure was studied by means of Mossbauer effect, magnetic measurement. X- ray diffaction and secondary ionmass spectroscopy (90-x) V_xZr_ (10) alloy are highly sensitive to the presence of hydrogen. The isomer shift (IS) has a small positive change and the magnetic properties transfer from magnetic to ferromagnetic state by hydrogenation, and the effect of hydrogen absorption to raise Fe magnetic moment (from the increase of saturation maguetization) and Curietemperature T_c from 257 to 384 K. F inally. The considerable increase of magnetic properties of amorphous Fe_ (90-x) V_xZr_ (10) alloy by hydrogenation is attributable to the change of hybridization effect between outer electrons of Zr atoms and 3d electrons of Fe atoms. From the results of SIMS experiment, it is noted that the hydrogen atoms are localized around Zrr whey hydrog en atoms enter into the allor.
