The structure of Nd5Fe2B6D4.1 contains two interstitial sites for deuterium atoms. Two environments for Fe are evidenced in the deuteride by Mössbauer spectroscopy. The Curie temperature of Nd5Fe2B6 is reduced after hydrogenation. Both Nd5Fe2B6 and Nd5Fe2B6D4.1 present a ferromagnetic structure. A small magnetic moment is found on iron for the boride, unlike the deuteride.
