Figure 2
Temperature dependent real part of dielectric constant (ε′) of KNN-xLS ceramics for (a) x = 0.015, (b) x = 0.03, (c) x = 0.045, and (d) x = 0.06 in the temperature range of 300 K–714 K for frequency 50 Hz to 100 kHz. The inset of (b) shows the variation of both transitions T C and TO–T with composition for KNN-xLS ceramics.
