چکیده انگلیسی


• The Co0.5Cd0.5Fe2O4 nanoparticles are synthesized using co-precipitation method.
• Powder X-ray diffraction patterns indicate the cubic spinal crystal structure.
• The saturation magnetization and the remanent magnetization increases after sinter.
• The FT-IR spectra confirmed the fundamental vibrations of host lattice.

Cd substituted Cobalt ferrite nano particles are synthesis using co-precipitation method. The as prepared samples are calcinated at 300 and 600 °C respectively. The existence of single phase spinal cubic structure of the prepared ferrite material is confirmed by the powder XRD measurement. The surface morphology images, compositional features are studied by SEM with EDX, and TEM. From the FT-IR spectra the absorption bands observed at 595 and 402 cm−1 are attributed to vibrations of tetrahedral and octahedral complexes respectively. From the VSM data, parameters like magnetization, coercivity, remanent magnetization and remanent squareness are measured. The saturation magnetization value is increases with increasing calcination temperature. The DSC and TG–DTA curves reveal that the thermal stability of the prepared ferrite nanoparticles. The calcination temperature affects the crystallite size, morphology and magnetic properties of the samples.
