초록

The dielectric and piezoelectric properties of Pb(Mn$\_$1/3/Nb$\_$2/3)O$_3$-Pb(Zr,Ti)O$_3$ceramics were investigated as a function of Zr/Ti ratio. Curie temperature was increased with the increase of Ti amount. At the Zr/Ti ratio of 0.495/0.505, dielectric constant and electromechanical coupling factor(kp) showed the maximum value of 1159 and 0.523 respectively.
