Abstrakt: High coercivity and saturation magnetization are well-known properties of the hard magnetic material cobalt ferrite (CoFe2O4). There are enormous prospects for a variety of biological, electrical, and recording applications due to many of these hard magnetic properties. The studies of Co0.5Cu0.5-xZnxFe2O4 (x = 0, 0.1, 0.2 and 0.3) samples using thermogravimetric, X-ray diffraction, scanning electron microscopy, and infrared technology are reported in this work. The biggest exothermic peaks were initially observed between 300 and 400 °C, and they were attributed to mass loss from the thermogravimetric breakdown of the nitrate and citrate content. At (111), (220), (311), (222), (400), (422), (551), and (555), X-ray powder diffraction patterns can be seen reflecting (440). It is discovered that the transmission bands fall within the range that was anticipated based on the spectra. The produced compounds are equivalent in terms of morphology and particle size, but they are somewhat aggregated as a result of interactions between magnetic nano-ferrites. Because the porosity decreases with increasing dopant concentration, the coercivity values of the synthesized samples rise with copper content. Each compound's resistance decreases as temperature rises, indicating that all samples exhibit semiconducting characteristics. [ABSTRACT FROM AUTHOR]
