Average magnetic moments of cobalt-base transition metal dilute alloys

Bulk magnetization measurements on binary and ternary cobalt-based alloys with transitional elements (Cr, Mn, Zr, Nb, Mo, Ru, Hf, Ta, W, Re, Os, Ir) confirm the existence of a periodic effect; the number of d electrons going from the spin-up band to the spin-down band depends on the series from which the transitional element is taken. The results are analyzed in terms of virtual bound states, experimental data giving the bound state position, obtained by dissolving a transitional impurity in a cobalt matrix, in relation to the Fermi level. Furthermore, there are no interactions between transitional impurities dissolved in cobalt at sufficiently small concentrations ( c < 5%)
