Abstract

The present paper reports the structural, magnetic and microwave properties of screen printed thick films of BaxSr1-XFe12O19 (BSF) (x = 0.0–1.0) synthesized via simple auto combustion technique followed by screen printing technique. The samples were characterized for various characterizations such as XRD, SEM, FT-IR, Micro-Raman, and VSM and microwave characterization. The X-ray diffraction patterns show that formations of hexagonal crystal structure with crystallite in the range 41.55 to 55.44 nm. The FT-IR and Micro-Raman spectroscopy also supports to the formation of hexagonal crystal structure with P63mmc space group. The surface morphology clearly reveals the distribution of Ba+2 ions on the surface of strontium hexaferrite. The substitution of Ba+2 ions strongly affect the saturation magnetization and microwave properties of barium strontium hexaferrite. The 60% Ba+2 ion substituted film shows maximum crystallite size of 55.44 nm and it shows highest magnetic moment of 76.62 emu/gm. The BSF thick films show broad band microwave absorption in the 8–18 GHz frequency range for all the compositions with a maximum of around 68% for the 60% Ba+2 ion substituted film.
