N2 - 57Fe Mössbauer spectroscopy has been performed for the paramagnet UFeGa5 and antiferromagnet NpFeGa5 (TN=118 K) at the temperature between 4.2 and 298 K. Hyperfine magnetic field Hhf at Fe nucleus of the NpFeGa5 reaches 1.9 T at 10 K. Observation of the quadrupole splitting at Fe sites below the Néel temperature implies that the origin of Hhf is not only due to the dipole field from magnetic Np atoms, but also from magnetic Fe atoms.
