Abstract
Temperature dependence of the hyperfine field and the isomer shift at (119)^Sn nuclei in fcc and hexagonal Co has been measured from 83˚K to 754˚K. The hyperfine field of fcc and hexagonal Co are 18.5 and 50.8 k0e respectively at 83˚K, 3-0 and 9.5 k0e at 673˚K. The dependence of the field on temperature is quite anomalous and shows a similar fashion in both structures. This dependence might be caused by the formation of localized moment at the Sn atom.
