Abstract

The hyperfine field distribution around cobalt impurities in iron has been measured by the continuous wave nuclear magnetic resonance method. Four distinct satellites are observable on the high frequency side shifted by 2.5%, 1.5%, 1.3% and 0.18% from the central resonance and an unresolved structure on the low frequency side. The hyperfine field shifts are positive at the four nearest neighbours and probably negative at the fifth and sixth neighbours. The concentration dependence of the average hyperfine field suggests a considerable conduction electron polarization contribution while the radial dependence reflects that of the moment perturbation. The temperature dependences of the satellites and main line frequencies follow the temperature dependence of the hyperfine field measured in pure iron.
