- Pb 1-x Co x Fe 12 O 19 nano-crystallites with an average crystal diameter varying between 74 and 86 nm are prepared via sol-gel auto-combustion. The X-ray diffraction (XRD) studies confirmed the single-phase P63/mmc space group. The surface morphology of the samples carried out using a field emission scanning electron microscope (FESEM) revealed the long hexagonal structure of the ferrites. Dielectric characterization is studied from room temperature to 800 K and in the frequency range of 100 Hz to 5 MHz. The ferrites exhibited two transition peaks in this temperature region which are attributed to phase transitions between ferroelectric to anti-ferroelectric and anti-ferroelectric to paraelectric phase. The composition x = 0.75 is suitable for high definition television deflection yokes for it has exhibited the highest dielectric constant, low ac electrical conductivity. Graphic Abstract
