Abstract

Pr-Co doped barium hexaferrites, having the general formula Ba1-x Prx Fe12-y Coy O19 (x,y = 0, 0.1,0.3) have been synthesized by citrate precursor technique. Powder X-ray diffractometer, Scanning electron microscope (SEM) and diectric measurement instruement were used for the characterization of the prepared samples. X-ray diffraction confirms all the samples exhibits single hexagonal phase with space group P63 /mmc. . It is observed that the lattice parameter (a) and (c) decreases with the substitution. The unit cell volume also shows the same pattern. The average grains size was found to vary with Pr-Co substitution. The dielectric constant and dielectric loss were examined as a function of frequency. There is decrease in dielectric constant at lower frequencies and constant behavior at higher frequencies which is a general trend of ferrites.

Keywords: Hexaferrite, SEM, Dielectric constant.
