AbstractResults of charge-transport and magnetic measurements of nanotubular polyaniline (PANI) composites containing Fe3O4 nanoparticles (similar to10nm) synthesized by a "template-free" method are reported. The T-1/2 resistivity has been observed, and dc magnetic susceptibility data are fitted to an equation chi = chi(P)*+ C/T. With increasing weight ratio of Fe3O4, the electrical conductivity and temperature-independent susceptibility chi(P)* increase, and the Curie-type susceptibility is suppressed at low temperatures. Further discussions have been given. The PANI-H3PO4/Fe3O4 composite containing 27wt% of Fe3O4 nanoparticles is superparamagnetic, exhibiting very little hysteresis even at 5K.
