On Suhl's dispersion equations for dilute magnetic alloys in a finite magnetic field

I. Exact Reduction to a Single Integral Equation

  • Published:
Zeitschrift für Physik B Condensed Matter

Abstract

The system of six coupled, nonlinear, singular integral equations, devised by Suhl to treat the problem of a spin 1/2 magnetic impurity in a finite magnetic field is shown to be reducible to a single integral equation. Analytic properties and symmetries of the system are discussed, which may serve as a guideline for numerical studies of the final integral equation. The first few steps of an iteration in terms of the magnetic field strength are carried out analytically.
