Dielectric properties of Pb(Mg 1/3Nb 2/3)O 3 - PbTiO 3 single crystals grown by a modified Bridgman method are investigated under strong, high frequency (>100 kHz) AC field. It is found that there is a phase transition due to the applied AC field, which may be due to the following reasons: (1) strong AC field quickly switches the polarization directions of domains that heats up the crystal due to the friction of domain change; (2) phase transition happens because of the increase of the temperature. Comparing with conventional heating techniques, AC field induced phase transition is a quicker and more effective way. Experimental results confirm the increase of d 33 and the change of transmittance under strong AC field.
