Abstract
Nanocrystalline spinel ferrite of composition Cu0.2Ni0.2Mg0.2Ca0.4Fe2O4 is synthesized by wet hydroxyl co-precipitation method in ethylene glycol as chelating agent and sodium hydroxide as precipitator at pH 8. Ethylene glycol is utilized as the medium which serves as the dissolvable and in addition a complexing specialist. The synthesized particles are annealed at various temperatures. Thermogravimetric investigation affirms that at 280°C ethylene glycol is dissipated totally and stable phase arrangement happens over 680°C. FTIR spectra of as synthesized and annealed at 1050°C recorded between 400cm−1 and 4000cm−1. Structural characterizations of all the samples are carried out by X-ray diffraction (XRD) technique. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) affirm that the particles are spherical and cubic shape with the crystallite size of 12nm to 32nm. Magnetic measurements are performed utilizing vibrating sample magnetometer at room temperature.
