Hyperfine Magnetic Fields at Nuclei of Indium in Iron and Nickel

Hyperfine magnetic fields for In in Fe and Ni were determined by nuclear orientation of ${\mathrm{In}}^{114m}$ in Fe and Ni alloys. A ${\mathrm{Co}}^{57}$ thermometer was used in each case. The results are: $H_{\mathrm{hf}} \left(\mathrm{In}\mathrm{in}\mathrm{Fe}\right)=-295\mathrm{}\pm 10$ kG; $H_{\mathrm{hf}} \left(\mathrm{In}\mathrm{in}\mathrm{Ni}\right)=-42\mathrm{}\pm 5$ kG.
