On the theory of the adsorption of atoms onto a metal surface in the presence of an external quantizing magnetic field

The Anderson-Newns model for the adsorption of atoms onto metals is generalized to the case of the presence of an external transverse quantizing magnetic field. Analytical expressions for the density of metal states in the external magnetic field are obtained. Analytical expressions for the density of adatom states are obtained in the approximation taking only the change in the density of substrate states into account. The charge exchange between the adatom and the metal is studied. The dependences of the density of adatom and transition-charge states on the magnetic field are studied for different values of the interaction constant. An analytical expression for the density of substrate states perturbed by adsorption is obtained.


Relaxation and thermodynamic parameters of the theory of spin-wave damping in low-dimensional magnetic materials

Pleiades Publishing Ltd
Several basic parameters of the surface spectrum of a system are estimated with respect to the spin-spin interaction. An expression for the surface relaxation time and its numerical estimation are given. The dependence of the relaxation time on the geometric factor determined by the surface geometry only is presented. The conditions for the resonance absorption of spin-wave energy by the surface are considered. Certain expressions for the thermodynamic potentials taking the effect of surface resonance on the equilibrium properties of the system into account are given.
