Abstract

Magnetic barium cobalt hexaferrite particles-PVA composites with of different mass ratio: 9:1, 8:2, 7:3, 6:4 and 5:5 were prepared. Structural properties of the composites were characterized by Infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). The effect of the concentration of Ba2Co2Fe28O46 hexaferrites on structural and dielectric properties of magnetic-PVA composites were investigated. FTIR result revealed that composite samples show absorption peaks of both ferrites and PVA. The X-ray diffraction investigations confirm the formation of mono phase of hexaferrite particles. Scanning electron microscopy images reveal that the shape and size of barium cobalt hexaferrite powder particles is irregular. The addition of PVA not much changed the shape and size of particles (ranging from 200-300 nm) but porosity found to decrease.
