The magnetic hyperfine interaction for 119 Sn impurity atoms in the GdMnSi host has been studied by Mössbauer spectroscopy. The hyperfine field for Sn atoms at 5 K is B hf = (−27.6 ± 0.3) T. The temperature dependences of B hf and magnetization are practically identical. As follows from the comparison of the results to data for GdCoSi host and an analysis of the satellite structure of the spectrum in Gd 0.95 Y 0.05 MnSi host, the contribution to the transferred hyperfine field from 3d moments in GdMnSi vanishes. Both experimental results and obtained empirical function of the radial dependence of the gadolinium contribution to B hf emphasize the short‐range nature of the hyperfine interaction for Sn impurity atoms in Gd‐based magnetic alloys.
