Local magnetic- and hyperfine-field properties of s–p, noble and transition-metal impurities in Co host

Abstract We present a theoretical description of the local magnetic moment and hyperfine field of diluted s–p, noble and transition metal nd impurities (n=3,4,5) in Co host. The cases of s–p and noble impurities (Cu, Ag, Au) are described within an extension of the Daniel and Friedel model. The case of nd impurities is described within the classical picture of Wolff–Clogston. The calculated hyperfine fields for all the impurities are in excellent agreement with the observed experimental data.
