Magnetic Moment Distributions in Dilute Nickel Alloys

摘要: A neutron scattering technique has been developed which enables the spatial distribution of magnetic moment disturbance around an impurity atom in a ferromagnet to be examined over distance several Angstroms. Measurements show that when vanadium or chromium is added dilutely nickel resulting occurs not only at sites themselves, but also on neighboring sites. In fact, most change saturation magnetization observed alloying due decrease moments atoms vicinity solute rather than changes positions. On other hand, if iron manganese appears confined atoms. These results are discussed terms theory suggested by Friedel.
