A theory is presented for the effects of the atomic environment on the stability of localized magnetic moments, on the temperature at which the spins of a cluster of magnetic atoms appear, order, and at which magnetic order among different magnetic clusters occurs. It is argued that the covalent splitting of the d-electron states causes the appearance and quenching of the magnetic moments in CuNi and AuV alloys. The predicted persistence of magnetic moments above the Curie temperature in CuNi is supported by the electrical resistivity and photo-emission. The paper discusses also how spin-orbit coupling affects magnetic moments. Author
