Abstract
The drop of ferromagnetic moment in the ternary solid solutions Nil-x-yCuxDy, (D= Zn, Si, Au, Al) is analyzed in terms of the statistical model of the environment dependent moments. This probabilistic model shows that the disappearing of one Ni atom ferromagnetic moment can be assigned to the replacement of at least four Ni-Ni bindings, out of twelve, in pure nickel. This paper aims at discussing all these features that, from the point of view of macroscopic equilibrium states, are related to the distribution of local bonds, provided by the peripheral electrons of the substitute atoms dissolved in the Ni matrix.
