The hard magnetic alloy “alnico 8” is investigated by Mössbauer spectroscopy. Two non‐equivalent positions are found for the Fe atoms in the hardened alloy. After tempering and a magnetic‐field heat treatment cycle (MFT) some of the Fe atoms are found to have a paramagnetic environment. The MFT has the effect of increasing the fraction of the Fe atoms which have such an environment and a maximum value of 7% is obtained for this fraction. The magnetic fields at the Fe 57 nuclei are determined for various states of the alloy. The results are discussed together with the results of Mössbauer investigations of “alnico 5”.
