Figure 4.

Dielectric constant and dielectric loss of PMNT/ZnO ceramics measured at room temperature. The upper group showed the relation of dielectric constant and ZnO content. The other lower group showed the relation of dielectric loss and ZnO content. These values were obtained from sample measurement at frequencies of 1 kHz (black line and square symbol), 100 kHz (red line and circle symbol), 500 kHz (blue line and triangle symbol), and 1 MHz (green line and tilted square symbol).
