Abstract: 
In this research, first, nanoparticles of SrFe11. 98Mg0. 1Sn0. 1O19 hexaferrite was synthesized via sol-gel auto-combustion process and then the nanocomposites of hexagonal ferrites/perovskite with the amounts of SrFe11. 98Mg0. 1Sn0. 1O19/BaTiO3 (50/50, 40/60, 70/30 w/w) was prepared by the ball-milling method. Fourier transform infrared (FTIR) spectrums of SrFe11. 98Mg0. 1Sn0. 1O19, was shown that the bands at about 400 and 500 cm-1 proved the formation of nano hexagonal ferrites. On the FTIR spectrum of nanocomposites, the Ti-O bond of perovskite appeared. X-ray diffraction (XRD) analysis was confirmed the formation of hexaferrite and perovskite phase of BaTiO3. Field emission electron microscopy (FESEM) pictures have represented the formation of hexagonal nanoparticles and sphere shape of BaTiO3. Vibrating sample magnetometer (VSM) hysteresis loop was revealed that SrFe11. 98Mg0. 1Sn0. 1O19 belonged to the soft magnetic materials due to the 604. 45Oe coercivity. By formation of nanocomposites, the coercivity was increased up to 1500 Oe. Vector network analyzer (VNA) analysis was revealed the maximum absorption of-16. 4 db at 11. 5 GHz frequency for SrFe11. 98Mg0. 1Sn0. 1O19/BaTiO3 (60/40) nanocomposite sample.
