The effect of hydrogen on the magnetic properties of crystalline Zr–Fe alloys was investigated by applying the 57 Fe Mîssbauer spectroscopy. The hyperfine magnetic field distributions have been calculated. It turned out that the nature of the early appearance of ferromagnetism in hydrogenated zirconium‐based alloys is not only affected by the decomposition of zirconium‐rich intermetallic compounds into ZrH 2 and ZrFe 2 but also by the rearrangement of the near neighborhood of Fe atoms within α‐Zr due to interstitial hydrogen providing to Fe–Fe interactions and the formation of magnetic clusters.
