Structural disorder influence on charged and magnetic impurity states

Charged and magnetic states of impurity dissolved in amorphous metallic alloy are investigated. Hamiltonian of system is generalization of Anderson impurity model and includes additionally the process of elastic and non-elastic conductive electrons scattering on ions of metal and on charged impurity. Configurational averaged one-particle Green's functions are obtained within the Hartree-Fock approximation. The system of self-consistent equations for the calculation of the electronic spectrum, the charged and the spin-polarized impurity states are given. Qualitative analysis of the influence of the metallic host structural disorder on observed values is given. Additional shift and broadening of virtual impurity level is caused by structural disorder of impurity environment.
