| Abstract | ||
| This research included the preparation of films from (polymer-ferrite) compounds (FRCs). The ferrite was of the chemical composition (Ba1-x Srx Fe12 O19 ) of the (M-type) when (X = 0.0.6), as well as pure rubber and ferrite compounds, and the rubber was of the three types. (T484, CQR, EGI), the films were deposited on slldes of glass by casting method. The optical properties of these compounds were measured using the ultraviolet spectrum and within the wavelength range (300-800) nm. The absorbance (A), transmittance (T) and reflectivity were determined. (R) The absorption coefficient (α), optical energy gap (Eg), extinction coefficient (K), refractive index (n), real (Є´) and imaginary (Є´´) dielectric constants, and optical conductivity (σa.c ) were also estimated, knowing The value of the absorption coefficient (α) was identified. The nature of indirect electronic transfers was identified, and the energy gap values ranged between (1.79-3.83) eV. The largest value was for the pure Ferrite/T484 compound, indicating that these compounds have good insulating properties | ||
