Abstract
Numerical results are presented from the study of local environment effects on the magnetic properties of atoms in simple models corresponding to the three typical alloys rh-ni, rh-pd and cu-ni. It is shown that (i) the dependence of the susceptibilities upon concentration and environment, (ii) the importance of the selfconsistent calculation of the charge transfers and the energy levels, (iii) the connection between the relative position of the energy levels and the relative magnitude of the susceptibilities, and (iv) that the susceptibility of the central atom is mainly determined by the electron-electron interactions on the central atom for rh-ni and rh-pd but that in cu-ni atoms further than the first neighbours need to be considered.
