Effect of annealing temperature on structure, electrical and magnetic properties of polyaniline cobalt ferrite composite

Abstract EN

PANI/CoFe2O4 nano composites were synthesized by solid state reaction with different amounts of the CoFe2O4 nanoparticles (0.5, 1& 1.5 gm).

The structural, thermal and magnetic properties of the synthesized PANI/CoFe2O4 were studied.

The AC conductivity (σac) was studied as a function of frequency up to 10 MHz.

The results confirmed the formation of PANI/CoFe2O4 composites.

Both of DC and AC conductivities recorded unsaturated behavior with increasing ferrite content.

The Magnetic characteristics were carried out at room temperature and were found to be strongly dependent on the nature of magnetic particle size and separation distance between them.
