Abstract
57Fe Mössbauer measurements of NpFeGa5 has been carried out in external field Hex = 0, 10 kOe. The negative quadrupole splitting QS was enhanced between 70 and 110 K. Negligibly small QS in the paramagnetic state was verified by a measurement of the spectrum in the applied field of 10 kOe. A correlation between the magnetic state and the electric field gradient implies that the origin of Hhf is not only due to the dipole field from magnetic Np atoms, but also from magnetic Fe atoms.
