以(FeCl3，6H(2)O)、(NiCl2，6H(2)O)、(CuCl2，4H(2)O)、NaOH和酸性油酸为原料，采用化学共沉淀法合成了CuxNi1-xFe2O4(x=0.0，0.2，0.5，0.8，1.0)纳米铁氧体粉末。用X射线衍射仪对所合成的粉末进行了表征，并对其结构性能进行了测定。用透射电子显微镜和扫描电子显微镜对产物的形貌和粒径进行了测定。用傅里叶变换红外光谱(FT-IR)对铁氧体的结构进行了研究和确认。用拉曼光谱验证了我们已经合成了CuxNi1-xFe2O4，并测定了它们的声子模。热重分析结果可以确定样品的热循环，而差热分析结果可以确定相变温度。利用光学研究中的紫外可见光谱来计算带隙能。利用振动样品磁强计获得了磁滞参数。综上所述，X射线衍射仪证实了单相尖晶石结构。晶格常数随铜含量的增加而增大。纳米粒子的尺寸随着铜含量的增加而减小。CuxNi1-xFe2O4的磁性随Cu2+的变化而发生显著变化，其中铜取代度的变化对材料的光学、晶粒度和磁性有显著的影响。合成的铁氧体平均晶粒度为14~43 nm。
The CuxNi1-xFe2O4 (x = 0.0, 0.2, 0.5, 0.8, 1.0) nanoferrite powder were synthesized through chemical co-precipitation method using only (FeCl3, 6H(2)O), (NiCl2, 6H(2)O), (CuCl2, 4H(2)O), NaOH and acid oleic as raw materials. The synthesized powder was characterized by X-ray diffraction (XRD); it was used to determine the structural properties. The transmission electron microscopy and the scanning electron microscopy were used to determine the morphology and particle size. The Fourier Transform Infra-Red (FT-IR) spectroscopy is used to deduce the structural investigation and confirmation of ferrite. Raman spectroscopy is used to verify that we have synthesized CuxNi1-xFe2O4 and determines their phonon modes. The thermo gravimetric analysis findings allow the thermal cycle determination of samples whereas differential thermal analysis findings allow the phase transition temperature identification. The optical study UV-Visible is used to calculate the band gap energies. The vibrating sample magnetometer was used to obtain the hysteresis parameters. In conclude, the XRD confirmed the single phase spinel structure. The lattice constant increased with the increased copper contents. The size of nanoparticles decreased with the increased copper contents. The magnetic property of the CuxNi1-xFe2O4 shows remarkable changes with change of Cu2+.The variation of copper substitution has a significant influence on the optical, grain size and magnetic properties. The mean crystalline size of the synthesized ferrite was in the range of 14-43 nm.
