摘要：

Perovskite-type Pb(Mg1/3Nb2/3)O3 (PMN)-based ceramics were prepared by modifying La(Mg2/3Nb1/3)O3 and PbTiO3. Dielectric and electrostrictive properties of modified PMN-based ceramics were investigated from the viewpoint of actuator materials. The temperature dependence of the dielectric constant, epsilon(s), shows a broader peak compared with that of pure PMN in the vicinity of room temperature. Transverse electrostrictive strain, S = -3.0 x 10(-4), was induced under an applied electric field of 10 kV/cm.
