In this work, the electrical conductivity and magnetic properties of Fe_3O_4C electrospun composite nanofibre was studied. Polyaery lonitrile (PAN) solutions containing (10wt.% Fe_3O_4) magnetite nanoparticles were electrospun and pyrolized at two different temperatures 700°C and 900°C for a comparative study and as a result, electrically conducting magnetic carbon nanofibre composites were produced. The electrical conductivity was measured using four-point probe method and magnetic properties were also obtained using Superconducting Quantum Interference Devices (SQUID). Electromagnetic composite nanofibre with the electrical conductivity of 9.2S/cm and saturation magnetization equal to 16emu/g was acquired. The most appropriate carbonization temperature to produce highly conductive carbon fibre composites was 900°C. SEM and TEM were used for investigating the morphological characteristic of these electrospun composite nanofibres.
