Magnetic Moment Distributions in Dilute Nickel Alloys
Journal Article

· Journal of Applied Physics
A neution scattering technique was developed that enables the spatial distrubution of the magnetic moment disturbance around im impurity atom in a feriomagnet to be examined over a distance of several Angstroms. Measurements show that when vanadium or chromium is added dilutely to nickel the resulting magnetic disturbance occurs not only at the impurity atom sites themselves, but also on the neighboring nickel sites. In fact, most of the change in saturation magnetization observed on alloying is due to a decrease in the moments on nickel atoms in the vicinity of solute atoms rather than to changes in moment at the impurty atom positions. On the other hand, if iron or manganese is added dilutely to nickel the moment disturbance appears to be confined to the solute atoms. These results are discussed in terms of a theory suggested by Friedel. (auth)
