Investigations of structural and magnetic properties of Cu1-xVxO nanostructures prepared by sol-gel method

Abstract Cu1-xVxO Nanoparticles (where x = 0.00, 0.10, 0.20, and 0.30), were synthesized using the sol-gel method. The prepared powders were investigated using different characterization methods such as X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and a vibrating sample magnetometer (VSM). The XRD patterns of the synthesized samples clearly indicated a polycrystalline structure with a monoclinic phase. What is more, some diffraction peaks such as V2O3, V3O5, and VO2 appeared with increasing mixed vanadium. The nano-sized synthesized powders were identified by FE-SEM and revealed a semi-spherical morphology with some agglomeration. The VSM results indicated that the magnetic properties were dependent on the vanadium content. The saturation magnetization (Ms) increased monotonously from 0.2075 to 0.4836 emu/g as the vanadium content increased.
