Abstract

⁵⁷Fe Mössbauer measurements of NpFeGa₅ has been carried out in external field H_ex = 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 H_hf is not only due to the dipole field from magnetic Np atoms, but also from magnetic Fe atoms.
