Description
Summary:The local susceptibility and 3d-spin dynamics of isolated Fe ions recoil implanted into alkali-metal hosts is measured by the perturbed- gamma -ray-distribution method. The observations of extremely large values for the hyperfine fields and magnetic moments and of an extremely small spin linewidth and quantitatively consistent with a stable 3d exp 6 configuration of Fe exp 2+ ions in spin-orbit coupling along with a negligible crystal-field splitting. Iron in Li strongly deviates from the magnetic behavior of a purely ionic configuration. The results permit a comparison of local-moment formation of 3d and 4f systems. 14 ref.--AA
