Abstract

For proper applications of the Stoner condition, we describe the assumptions in its underlying theory and their implications that need to be considered in practice. The nature of Stoner exchange parameters is examined based on spin-polarization perturbational orbital theory and a connection has been made in understanding the parameters with both local spin density and Hartree-Fock approximations via a self-interaction-corrected local spin density (SIC-LSD) exchange-correlation functional.
