Abstract

We report the nonaqueous synthesis and magnetic properties of narrowly size distributed ZnFe₂O₄ nanocrystals of two different particle sizes by nanoemulsion, of which structure and properties were investigated by transmission electron microscopy, x-ray diffraction, vibrating sample magnetometry, and physical property measurement system. The morphological and structural characterization show the high crystallinity and excellent particle size distribution of the ZnFe₂O₄ nanocrystals in the diameters of 5.37 ± 0.68 nm and 6.44 ± 0.95 nm, separately. Meantime, the corresponding magnetic measurements reveal the strong size dependence and well-defined nanomagnetism of the nanocrystals.
