Abstract
Nanocrystalline Li0.5Fe2.5−xCoxO4 (2.5≥x≥0) system was prepared by sol–gel route. Formation of single phase cubic spinel structure for all the compositions was confirmed from their X-ray diffraction studies. These ferrite samples existed as homogenous and uniform grains as observed from Scanning Electron Microscopy technique. The magnetic studies indicated that, the ferrimagnetic behavior decreases with Cobalt substitution. In general, the substitution of cobalt plays an important role in changing the structural and magnetic properties of these ferrites.
