Investigation of magnetic and structural properties of copper substituted barium ferrite powder particles via co-precipitation method

In this paper, it is proposed to synthesize copper-doped barium ferrite (BaCuxFe12−xO19) using co-precipitation technique at different ratios in order to increase the coercivity value which in turn increases the magnetic storage capacity of the copper-doped barium ferrite powder. This technique is very compactable with lower cost. This method was used to prepare different ratio (0–8%) of copper-doped barium ferrite samples exposed to sintering process under the temperature 1200 °C for 6 h because the base and doped materials are combined to form a new compound. The sintered compound is involved the XRD analysis and the obtained values are matched with the constant standards (a = b = 5.864 Å and c = 23.098 Å). Hence, the samples proved as hexagonal system. TGA/DTA used to establish selected characteristics of materials that exhibit decomposition and oxidation process. FT-IR spectroscopy used to confirm the chemical bonds and vibration mode of samples. Using beam of X-rays, XPS spectra obtained and the binding energy of the sample is measured. From the SEM analysis, the morphology and grain size of the copper-doped barium ferrite powder materials are found. The vibrating sample magnetometer measures the magnetic saturation, magnetic reminisce and coercivity of a sample. The magnetic saturation, magnetic remanence and coercivity values are found and tabulated.
