Local Environment Effect on the Atomic Magnetic Moment in Ferromagnetic Transition-Metal Alloys. II. High-Field Susceptibility

Abstract

The susceptibility to the homogeneous magnetic field is calculated at the absolute zero of temperature for several ferromagnetic transition-metal alloys (bcc Fe–Ni, Fe–Co and Fe–V) by use of an effective-medium theory of local-environment effect developed by Hamada and Miwa within the Hartree-Fock approximation. It is shown that the susceptibility is sometimes dominated by the atom with a particular local environment. The effect of the deformation of the local density of states due to the magnetic field is discussed in detail.
