摘要：

In3+ incorporated lithium ferrites have been synthesized via sol-gel auto-ignition route, and these were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and vibrating sample magnetometer (VSM). Thermal analysis of pure sample shows 12% weight loss in three successive steps observed by Thermogravimetric analysis (TGA). The lattice constant, cell volume, radii (Rt and Ro), and hopping lengths exhibited decreasing behavior, while crystallite size, X-ray, and bulk densities show an increasing trend with indium substitution. The bond length of each side decreases as indium content increases. The squareness ratio (R) exhibited that synthesized ferrites are single domain. The moderate value of saturation magnetization with a small Hc and squareness ratio proposed that synthesized ferrites may be suitable for high-frequency applications.
