Kurzfassung:
The authors report a giant piezoelectric coefficient, −d31=2000pm∕V in substrate-free polycrystalline (Pb(Mg1∕3Nb2∕3)O3)0.63(PbTiO3)0.37 (PMN-37PT) sheets at E⩾7kV∕cm, larger than the −d31=930pm∕V exhibited by specially cut commercial PMN-PT single crystals and 300–500pm∕V of polycrystalline bulk PMN-37PT. X-ray diffraction indicated due to the thin sheet geometry the present PMN-37PT sheets contained about 60vol% of the tetragonal a and rhombohedral domains even after poling. At large fields, these tetragonal a and rhombohedral domains switched to the tetragonal c domains to result in the giant d31 enhancement at high fields.
