Abstract :

Nano ferrites shows its striking outlook with both scientific and technological significance in most promising pertinent applications such as, biosensors, magnetic separation and photo catalytic applications. In this investigation, the study was engrossed on the progression of group IV element of zinc ferrite tailored via co-precipitation method. On doping lanthanum ion in ZnFe2O4 appears to be a fruitful approach to apprehend better physical properties of the lattice, which can be conveniently used magnetic, optical, and electrical properties of the as-synthesized nanocrystals. XRD analysis elucidates the cubic phase formation and lattice parameter, whereas the FTIR spectrum reveals the absorption band between 4000- 400 cm-1 confirmed the cation vibration of the spinel structure. TEM micrograph image depicts the surface morphology and particle pattern. UV-visible spectral analysis reveals the significance of optical properties and the band gap was found using Kubelka-Munk plot and further the magnetic behaviour was evaluated using a VSM, under an applied magnetic field of 10 kOe. The results shows that doping the lanthanum ion in ZnFe2O4 tend to decrease in saturation magnetization as well as in anisotropy due to their enhancement of crystallite size andcation distribution.
