The nano crystalline BaGd 0.1 Fe 1.9 O 4 spinel ferrite and polypyrrole were both fabricated using sol–gel technology. The nanocomposites must be produced consisting of BaGd 0.1 Fe 1.9 O 4 ferrite were combined with polymer. According to the XRD analysis, the trace amounts of gadolinium ions were successfully incorporated into the spinel lattice. The crystallite size of the nanocomposites was varying from 30 to 56 nm. The nanoparticles that were embedded in the PPy matrix and acted as a block to the conduction mechanism were responsible for the increased activation energy as well as the resistivity. When placed in a magnetic field, these nanocomposites showed hysteresis loops, attesting to their ferromagnetic nature. Saturation magnetization and coercivity of nanocomposites are the two magnetic characteristics that change as the concentration of ferrite particles is increased. Ferromagnetic ferrite/polymer composites have been suggested for use in microwave absorbing applications, with PF4 compositions being considered.
