Magnetic Moment Distributions in Dilute Nickel Alloys

A neutron scattering technique has been developed which enables the spatial distribution of the magnetic moment disturbance around an impurity atom in a ferromagnet 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 …
