Fig. 1From: Structural and Magnetic Properties of Transition-Metal-Doped Zn 1−x Fe x OSchematic diagram of 2 × 2 × 2 ZnO supercell with a hexagonal wurtzite structure. The numbers on the spheres indicate the atomic positions substituted by Fe cations in subsequent first-principle calculations. The atom labeled 1 is the reference positionBack to article page
