Synthesis and characterization of Li substituted Ni-CoFe₂O₄ Nanopowder by Using Sol-Gel Method

Lithium substitute Nickel-Cobalt nanoferriteare Co-Ni Li_(x)Fe_2-x O₄(where x=0.05, 0.075, 0.1) Nano ferrite powders were synthesized by sol-gel method it is simple and cost effective at low temperatures. Nickel ferrite is a typical soft and ferromagnetic material with a completely inverse spinel structure, has a large number of applications. The present work is to study structural and magnetic properties of the synthesized samples. The role of Li (Lithium) substituted Ni (Nickel)-Co (cobalt) shows the formation of crystal phase, which was identified by X-ray diffraction method. The lattice constant increases with the increasing in Li contain. The prepared samples were characterized by X-ray diffraction and hysteresis loop. From XRD characterization the structure of the material is found to be spinel ferrite. The average particle size is in range of 52 to 64 nm. The magnetic properties were studied by hysteresis loop.
