The angular distributions of γ rays and α particles from oriented 250Bk, 253,254Es, and 255Fm nuclei were investigated to extract hyperfine interaction information for these actinide impurities in an iron host lattice. The hyperfine field of einsteinium in iron was found to be |Bhf(EsFe̲ |)=396(32) T. With this value the magnetic moment of 254Es was then determined as |μ|=4.35(41) μN.
