Fiber shape Polyaniline coated on BaSrFe12O19 nanoparticles were synthesized successfully in the presence of DBSA as dopant and template. The products were characterized using SEM, FT-IR, EDX, DRS, UV-visible, XRD, VSM analyses. The DC conductivity was measured using four-wire-technique and finally vector network analyzer was employed to determine the ability of composites in microwave absorption at the range of 8-12 GHz. Results proven that coexistence of magnetic phase with conducting phase results in enhancing electromagnetic wave absorption, and a minimum reflection loss of −15.1 dB at the frequency of 10.2 GHz was obtained
