| Description | A detailed theoretical study of structural and magnetic behavior of iron, cobalt, and nickel along the trigonal transformation paths at various volumes per atom is presented. The borderlines between various magnetic modification are shown for Fe and Ni. In the case of Ni, these phase boundaries between nonmagnetic and ferromagnetic phases occur even at the experimental value of volume per atom. On the other hand, Co keeps its ferromagnetic order in the whole region of the volume and shape deformation studied. Fe does not exhibit any transition between the ferromagnetic and nonmagnetic arrangement, but at low volumes per atom around the fcc structure, phase boundaries between the ferromagnetic high-spin, ferromagnetic low-spin, and antiferromagnetic states have been found. |
