MÖSSBAUER AND NEUTRON DIFFRACTION STUDIES OF NpRu2Si2

NpRu2Si2 has been studied by Mössbauer spectroscopy on powder samples and by neutron diffraction on a single crystal. Below TN=27.5 ± 0.5 K the magnetic ordering is incommensurate (k = [00k] , mk // k) Np moment values are not saturated and an incommensurate modulation is still present at low temperature (T/TN ≈ 1/20)
