Synthesis and Magnetic Properties of Hematite Particles in a “Nanomedusa” Morphology

Figure 2

(a) The experimental XRD pattern (orange trace) of the synthesized product consisting of the HNM particles and the small particles observed as a background in Figure 1(c). The total theoretical pattern of the HNM particles is shown by a black curve, whereas the difference is shown by the cyan trace. The arrow indicates the broad amorphous peak. (b) The theoretical XRD patterns of the two phases that constitute the HNM particles (both hematites with the same size of the unit cell, but different size of the crystalline domains). The narrow peaks (red curve) are associated with large crystalline domains, whereas the broad peaks (green curve) describe small domains. The calculated peak positions from the fitted model are shown as a stick pattern at the bottom.
