dc.description.abstract | It is well known that the coercivity of magnetic nanomaterials increases up to a maximum and then decreases to zero with decreasing particle size. However, until now, no single synthesis method has been able to produce magnetic nanoparticles with a wide range of sizes, i.e., from 10 to 500 nm, in order to uncover the coercivity evolution. Here we report the characterization of magnetite (Fe3O4) multi-granule nanoclusters (MGNCs) to demonstrate the transitional behaviour of coercivity. The M-H curves indicate that our samples had a relatively high saturation magnetization (M-S) value of similar to 70 emu/g and that the coercivity (H-c) increased to the maximum value of similar to 48 Oe until the nanoclusters reached a size of similar to 120 nm; the coercivity then gradually decreased to zero. | - |
