The infrared spectra of Li0.5TiXZnXFe2.5-2XO4 and Li0.5ZrXZnXFe2.5-2XO
4 ferrites were recorded by using Beckman Infrared Spectrophotometer i
n the range 200-800 cm-1. It has been found that there is no systemati
c variation in the band positions with Ti4+ and Zr4+ concentration. Th
is may be due to the difference in the microstructure of different fer
rites.
