Abstract: | The composite films prepared from weight fraction (0, 1, 3, 5 wt%) of cobalt ferrite powder and polymer polyvinyl alcohol (PVA) by the casting method. The cobalt ferrite powder were synthesized by sol-gel auto combustion as a chemical methods, sintered at (600oC) for 4 hours. The X-ray diffraction (XRD) pattern of powder showed single phase spinel structure. Optical microscope examination for composite films showed the homogeneity and have been studied dielectric properties (Dielectric constant ( ), Loss facter ( )) in rang (50Hz-3MHz).The value of ( ) and ( ) decrease with increasing frequency in the rang (50Hz-3MHz). |
