Abstract: The indium substituted cobalt ferrite having general molecular formula CoInxFe2-xO4 (for x= 0.0, 0.3,0.5) have been prepared by sol-gel auto combustion technique. The as prepared sample was sintered at 6000C for 4hr. The X-ray diffraction pattern reveals the formation of single phase indium substituted cobalt ferrite samples. The lattice constant obtained from XRD data increases with increase in indium substitution x. The Particle size obtained from XRD data is in the nanometer range. The particle size decreases with increase in indium substitution x. The average grain size obtained from Scanning electron microscopy technique is in nanometer range. The pulse field hysteresis loop tracer technique is used to determine the magnetic parameters such as saturation magnetization (Ms), remanent magnetization (Mr) remanent ratio and coercivity of the samples. The saturation magnetization (Ms), Magneton number decreases with increase in indium substitution in cobalt ferrite samples.
