Nonaqueous synthesis and magnetic properties of ZnFe 2 O 4 nanocrystals with narrow size distributions

We report the nonaqueous synthesis and magnetic properties of narrowly size distributed ZnFe 2 O 4 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,...

Description
Summary:We report the nonaqueous synthesis and magnetic properties of narrowly size distributed ZnFe 2 O 4 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 ZnFe 2 O 4 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.
