The Fe-57 Mossbauer effect measurements were carried out for Ni2Mn1-xFexGa with 0.3 <= x <= 0.7. The spectra were described satisfactorily with one Lorentzian sextet, which was consistent with the atomic ordering of the L2(1) structure. The obvious change in the absolute value of the Fe-57 hyperfine field (B-hf) at the martensitic transformation temperature was observed. B-hf at 80 K was 22.3 T and independent of x.
