Structural and magnetic modifications induced by hydrogen atoms occupying interstitial sites in GdNiInH0.5 compound

► We synthetized successfully the GdNiInHx hydride compound. ► The entrance of hydrogen atoms leads to an expansion of ∼2% of the unit cell. ► The intermetallic matrix shows ferromagnetic properties coming from Gd atoms. ► The magnetic properties of the intermetallic are affected by the entrance of H.
