Perovskite-type Pb(Mg 1/3 Nb 2/3 )O 3 (PMN)-based ceramics were prepared by modifying La(Mg 2/3 Nb 1/3 )O 3 and PbTiO 3 . Dielectric and electrostrictive properties of modified PMN-based ceramics were investigated from the viewpoint of actuator materials. The temperature dependence of the dielectric constant, ε s , shows a broader peak compared with that of pure PMN in the vicinity of room temperature. Transverse electrostrictive strain, S =-3.0×10 -4 , was induced under an applied electric field of 10 kV/cm.
