Variation in dielectric constant vs temperature. The inset shows the dielectric constant below 500 K both in the warming run and the cooling run for , 0.02, 0.04, 0.06, and 0.08 samples. All except the curves are shifted upward for clarity of the plot. The arrows and triangles indicate and , respectively.
Variation in and with . The lines are guides to the eyes.
Phase diagram for solid solutions, where , Ba, Sr, Ca, and . The lines are guides to the eyes. The inset shows the phase diagram for solid solutions. It clearly indicates that a B-site modification has a different effect on and .
