Magnetism in Spin-Density-Wave Chromium from First-Principles Calculation

Abstract

The electronic structure of the spin-density-wave state in chromium is calculated by means of the first-principles Korringa-Kohn-Rostoker Green function method within the framework of the local spin density functional formalism. Results of the calculation are found to be in good agreement with those of experiments concerning the magnetism in spin-density-wave chromium, that is, the amplitude of the fundamental wave and the ordering wave vector. The amplitudes of the harmonics of the spin density wave and concomitant charge density wave as well as the hyperfine field at a chromium nucleus are furthermore investigated.
