Polycrystalline zinc substituted lithium (Li-Zn) ferrite samples with chemical formula, Li0.5-x/2ZnxFe2.5-x/2O4(x = 0.6), were synthesized using sol-gel method. The synthesized powders were palletized and sintered at different temperatures starting from 500°C to 1000°C. XRD patterns of these samples confirm their single phase cubic spinel structure. The particle sizes obtained from XRD patterns using Debye-Scherrer formula were found to be in the range of 42 to 57 nm with almost a linear relationship between sintering temperature and particle size. Magnetization in these samples as a function of applied magnetic field was measured using vibrating sample magnetometer (VSM) and properties such as saturation magnetization (Ms) and coercivity (Hc) were found from M-H loops. It is found that Ms increases with increasing sintering temperature whereas Hc decreases. These variations in saturation magnetization and coercivity with sintering temperature are attributed to the corresponding variation in particle sizes.
