Abstract: Composites of ferrofluid-conducting polymer system have been prepared by co-precipitation and doping process. The prepared samples have been mainly characterized by FTIR, TEM, SEM, X-ray and EPR techniques. Relaxation behavior at room and liquid nitrogen temperatures, shape and size distribution of the composite gradients, sample crystallinity and the functional group attachment have been investigated. A probable schematic representation of composite formation has been described. It is observed that ferrofluid composite with saturation magnetization , <i style="">M</i>s = 90 gauss, has electrical conductivity of the order of σ = 1.0 <img src='/image/spc_char/cross.gif' border=0> 10<sup>-3</sup> Ω<sup>-1</sup>cm<sup>-1 </sup>which remains stable in gradient magnetic field
