Binary alloys of Fe_xTa_100-x (15≤x≤95) were fabricated by high rate sputtering. The amorphous state, as verified by X-ray diffraction, is realized over a wide composition range of 15≤x≤90. The amorphous alloys with Fe concentration up to the threshold x_c??65 are non-magnetic. For the samples with x>x_c, the magnetic ordering temperature (Tc) varies monotonically with Fe content to 200k for a-Fe_90 Ta_10. Measurement of the effective hyperfine field (H_eff) and the distribution of hyperfine field 〔P(H)〕have also been carried out. Small magnetic hyperfine field are observed, consistent with the small Fe magnetic moments measured. The concentration dependence of isomer shift and the electric quadrupole splitting have also been obtaind. The electric quadrupole splitting shows a large difference between Fe-rich and Ta-rich samples.
