The study on Dielectric and Strain Properties of ((1-y-x)Pb(Mg$_{1}$3 Nb$_{2}$3/)O$_3$-yPbTiO$_3$-xSrTiO$_3$Ceramics

(1-y-x)Pb(Mg$_{1}$3 Nb$_{2}$3/)O$_3$-yPbTiO$_3$-xSrTiO$_3$세라믹의 유전 및 변위 특성에 관한 연구

In this paper, Dielectric and strain properties of (1-x-y)PMN-yPT-xST Ceramics hale been investigated as a function of the amount of SrTiO$_3$(ST). The SrTiO$_3$ content is ranged from 0.01-0.05(wt%). As the amount of ST is increased, dielectric constant has a maximun value at 0.05 mol% composition. The Curie temperature is decreased linearly with increasing ST composition and Polarization properties have been investigated. Coercive field and remnant polarization has a maximum value at 0.01mo1% composiion.
