Structure and magnetism of iron and iron overlayers from the first principles
Friák, Martin ; Šob, Mojmír ; Vitek, V.
A detailed theoretical study of magnetic behavior of iron along the bcc fcc (Bain's) transformation paths at various atomic volumes is presented. The total energies are calculated by spin polarized full potential LAPW method and are displayed in contour plots as functions of tetragonal distortion c/a and volume; borderlines between various magnetic phases are shown. Stability of tetragonal magnetic phases of fl Fe is discussed. The calculated phase boundaries are used to predict the lattice parameters and magnetic states of iron overlayers on various (001) substrates.
