Structural, optical and magnetic properties of nanocrystalline zinc ferrite prepared by sol-gel method

Zinc ferrite nanoparticles were synthesized effectively by sol gel method and were annealed at 500°C. The sample was characterized by various techniques. Powder XRD, FTIR and FESEM studies were utilized to evaluate the phase structure and surface morphology. XRD revealed single phase spinel cubic structure of zinc ferrite. Light absorption and optical properties were deduced by UV-visible spectrophotometer. Magnetic properties of the sample at room temperature was deduced by vibrating sample magnetometer. The hysteresis loop depicted the ferromagnetic behavior of the sample.
