- The Cd0.9Co0.1Fe2O4 nanoparticles are synthesized using chemical co-precipitation method. The as-prepared samples are calcinated at 300 and 600 °C for 2 h. The thermal effects on structural, morphological and magnetic properties are reported. The X-ray diffraction data confirm the formation of single-phase cubic spinel structure. The Surface morphology and compositional features are studied using SEM with EDX and TEM measurements. The Magnetic properties of samples are evaluated using vibrating sample magnetometer. The magnetic properties, like saturation magnetization and coercivity are increases with increasing calcination temperature. The enhancement is attributed to the transition from a multi-domain to a single-domain nature. From the FTIR spectra, it is confirmed that the vibrations of tetrahedral and octahedral complexes corresponds to absorption bands at 590 cm−1 (ν1) and 460 cm−1 (ν2) respectively. The particle size enhances significantly with increasing the calcinated temperature. © 2015, Springer Science+Business Media New York.
