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

Figure 6

(a) A comparison of the curve of the HNM particles at K to the curves of the bulk hematite at in the weakly FM state (the “bulk WFM” curve) and at in the AFM state (the “bulk AFM” curve). The curves in the hysteretic region are shown on an expanded scale in the inset. (b) The curve of the HNM particles at K. The fit with (1) is shown by a black curve. The theoretical FM, AFM, and paramagnetic contributions are shown separately as well. The inset shows the experimental FM component only, obtained by subtracting the theoretical AFM and paramagnetic terms from the total experimental magnetization, .
