    Polypyrrole (PPy)/Fe3O4 nanocomposites were in situ synthesized using chemical oxidative polymerization in an aqueous solution of FeCl3.6H2O, in presence of different Fe3O4 loadings (0%–16.52%). These composites were characterized through a 4 Probe electrical conductivity measurement technique, Fourier Transform infrared spectroscopy, energy dispersive X-ray spectroscopy, scanning electron microscopy, X-ray diffraction, thermo gravimetric analysis, and vibrating sample magnetometer. Results showed maximum electrical conductivity of 75.28 S/cm for the 2.52% Fe3O4 loaded nanocomposite and with improved thermal stability compared with the host PPy. Furthermore, a linear relationship between saturated magnetization Ms and % composition of Fe3O4 in the above nanocomposites was observed, showing 6.34 emu/g at 16.52% Fe3O4/ PPy nanocomposite.
