الملخص EN

Nanocompound of BaAlyFe12−yO19, Ni0.5Zn0.5Fe2O4 and nanocomposite [x(BaAlyFe12−yO19) + (1 − x)Ni0.5Zn0.5Fe2O4] were prepared by Sol-gel method with a ratio x = 10, 25, 50, 75%.

the samples compressed as a tablet under 7 ton ⁄ cm2 hydraulic pressure, and these tablets were sintered at a temperature of 900 ℃ for a period of two hours (2h).

the X-ray diffraction revealed the hexagonal structure of BaAlyFe12−yO19 with lattice parameters c = 23.109 Å and a = 5.879 Å, while Ni0.5Zn0.5Fe2O4 reveals the cubic structure with a lattice parameter a = 8.358 Å.

the grain size of the samples has been calculated by SEM and it was between (25-35) nm.

electrical properties showed a decrease in the dielectric constant values, loss coefficient from (282.4348), (73.0997) to (4.2752), (0.4322) respectively, and increasing the electrical conductivity value from (2.2023 * 10-7 Ω-1 cm-1) to (9.1754 * 10-1 Ω-1 cm-1) with increasing the frequency.
