Abstract
The spinel ferrites Mg0.96Pr0.04Fe2O4 were synthesized by co-precipitate route. The in-situ polymerization technique is employed to prepare Polypyrrole. In present work, nanocomposites were manufactured by intermixing of Polypyrrole polymers and Mg-Pr-ferrites Mg0.96Pr0.04Fe2O4. The nanocomposites were subjected to characterization techniques like XRD (X-ray diffraction), SEM (scanning electron microscope) and VSM (vibrating sample magneto-meter). The XRD data confirmed the incorporation of praseodymium in spinel nano-ferrites. Non-homogeneous particle size distribution will be seen in SEM micrographs and core shell structure of prepared Nano-composites estimated. The hysteresis loop discloses the ferromagnetic nature of Nano-composites. The magnetic parameters like coercivity and saturation magnetization show variation with increase of ferrite additives. So, by controlling the amount of additives, one can acquire the desired properties. Two Nanocomposites FP1 = 25% and FP2 = 50% may be recommended for hyperthermia of cancer treatment.
