| Popis | 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 $\gamma$-Fe is discussed. The calculated phase boundaries are used to predict the lattice parameters and magnetic states of iron overlayers on various (001) substrates. |
