Abstract Using the57Fe Mössbauer effect the influence of the Ga content in amorphous (Fe1−x Ga x )84B16 on the average hyperfine fields $$\bar H$$ and isomer shift has been studied. For the sample (Fe0.98Ga0.02)84B16 the $$\bar H$$ , as well as the recoilless fraction,f a were measured as functions of temperature ranging from 12 K to 300 K. The experimental results show a linear correlation between Inf a and δ, and well as between δ andx. In the temperature range $$\bar H(T)$$ can be described by the Brillouin function and the second-order Doppler shift is appreciable. The characteristic temperature for such an amorphous alloy is 372 K. the effective vibrating massM eff=79 a.u.
