Figure 4
Atomic scattering factors f0 + for Fe2+, Fe3+ and Ti4+ against sinθ/λ for X-ray experiments at the Fe K pre-edge (E = 7.1085 keV). Since the cubic spinel structure has a center at the origin, the crystal structure factor lies near the real axis of the complex plane (see Table 2 ). Then, atomic scattering factors in this plot may be approximately expressed as f0 + . |
