Highly porous zinc ferrite (ZnFe2O4) nano-size powders are synthesized by varying fuel to oxidizer ratio. The metal nitrates are used as oxidizers while glycine is used as a fuel. The synthesis of material is carried out using an auto-combustion method. It is observed that the enhancement of magnetization occur with the enhancement of ‘Fuel to Oxidizer’ ratio i.e. Glycine to metal Nitrate (G/N) ratio...
Zn doped cobalt ferrites Co1−xZnxFe2O4 (x = 0.0, 0.1, 0.3) powders were synthesized by chemical co-precipitation method. Phase formation and crystalline nature was verified by using X-ray diffraction and Raman spectroscopy. The saturation magnetization (Ms), coercivity (Hc) and remanent magnetization (Mr) was recorded using vibrating sample magnetometer at room temperature. Magnetostriction measurements...
Mn has substituted part of Fe in cobalt ferrite (CoFe2O4) and resultant material has been abbreviated as CFMO (CoFe1.7Mn0.3O4). Chemical co-precipitation route has been followed for synthesis. X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDX), I-V measurement were performed for sample characterization. The influence of Mn substitution was seen...
