Synthesis, characterization and magnetic properties of ...

Aug 10, 2014· As the size of the hematite particle decreases to the micro/nanometer scale, materials can exhibit unusual magnetic behaviors that are quite different from those of conventional bulk materials (Sorescu et al. 1999). Figure 5 shows the magnetic hysteresis loops of AF, DF and GF at 300 K in the applied magnetic field sweeping from −20 to 20 kOe.
