A comparative study of dielectric and magnetic properties of Fe3O4 and CNTs-Fe3O4 composite has been reported in paper. In this, CNTs-Fe3O4 composites have been prepared by dispersing the CNTs in ionic (Fe+2/Fe+3, in 1:2) solution via chemical co-precipitation route. The dielectric properties of composites have been investigated in 101-106 Hz frequency range. The saturation magnetization (Ms) of CNTs-Fe3O4 composite is reduced. The dielectric permittivity of composites with increasing weight fraction of CNTs is also reduced which may be due to the space polarization of charges accumulated via conducting channels of CNTs.
