Theory for the Effect of the Local Atomic Environment and Spin-Orbit Coupling on the Formation of Local Magnetic Moments.

Abstract

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 Cu:Ni and Au:V alloys. The predicted persistence of magnetic moments above the Curie temperature in Cu:Ni is supported by the electrical resistivity and photo-emission. The paper discusses also how spin-orbit coupling affects magnetic moments. (Author)
