| The effects of diamagnetic bismuth substitution on the microstructural and magnetic properties of sol-gel auto-combustion citrate nitrate synthesized CuFe2-xBixO4 (x=0.0, 0.4, 0.8, 1.2, 1.6 and 2.0) nano powders were investigated. The samples were characterized by techniques such as X-ray diffraction, Raman spectroscopy, Fourier-transform infrared spectroscopy, field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, UV-Vis diffuse reflectance spectroscopy, and vibration sample magnetometer. The structural results showed a phase transition from a predominantly tetragonal structure with an I41/amd space group to a tetragonal structure with a P ncc space group. The magnetic properties of the samples revealed a transition from a ferrimagnetic to a diamagnetic phase due to the presence of the diamagnetic Bi3+. Although the coercive field exhibited a minimum value at a substitution level of x = 0.8, the saturation magnetization was found to decrease with increasing Bi substitution, ranging from 25.04 emu/g for x = 0.0 to -0.02 emu/g for x = 2.0. | ||
