The room-temperature second-, third- and fourth-order nonlinear dielectric constants of poled (1-x)Pb(Mg1/3Nb2/3) O3-xPbTiO3 single crystals were determined by measuring the dielectric response at a frequency of 10 kHz and under a dc bias of 0-1000 V/mm. Tunability of the apparent dielectric constan...
