.... The dielectric and ferroelectric properties of YCTO were investigated within the temperature range of 308–500 K and frequency range of 2 Hz–5 MHz. A characteristic dielectric anomaly was observed from 350 to 425 K. YCTO exhibited a broad dielectric peak which got suppressed and shifted to higher frequency region...

... spectrophotometer. The XRD analysis showed that the post-annealed BFO at 570°C possesses a perovskite structure and exhibits a rhombohedral structure without any impurity phase. A BFO ceramic capacitor (indium tin oxide (ITO)/BFO/gold (Au)) was fabricated using gold and ITO as electrodes. The ferroelectric property...
