Abstract

The present study of Np2Ir2In completes the 237Np Mössbauer spectroscopy investigations of Np2T2X (T = Co, Rh, Ir, Ni, Pd, Pt; X = In, Sn) compounds. Np2Ir2In is found to order at T ord≈30 K and the complex Mössbauer spectra suggest the occurrence of a noncollinear modulated magnetic structure with an average magnetic moment on the neptunium μNp≈0.76 μB. The magnetic properties of Np2Ir2In are consistent with the general trends observed in the An2T2X (An =U, Np) isostructural family.
