Diverse physical characteristics of mixed Li-Mg spinel ferrite thin films fabricated by spray pyrolysis technique

Nanocrystalline Li0.5-x/2MgxFe2.5-x/2O4 (0.0< 1.0) thin films have been effectively fabricated by spray pyrolysis technique. These films show monophase cubical construction as appeared in the XRD patterns and also validated by FTIR spectroscopy. The optical energy band gap values were obtained in the range of 1.78-2.52 eV. The excitation wavelengths were found to be in between 400 and 410 nm which attributed to the holes and electron in photoluminescence spectra. VSM results reveal that magnetic parameters lowered with Mg2+-substitution in Li0.5Fe2.5O4. The incorporation of Mg2+-substitution in pristine lithium ferrite thin films promotes the tailoring of the structural, optical and magnetic properties.
