Samples were poled at -40 degreesC and the piezoelectric properties were measured by resonance-antiresonance method. Q(m) increased by increasing the doping contents of Mn. When 0.5 wt.% MnO2 was doped, Q(m) increased from 95 to 480. From the experimental results, it is predicted that Mn behaves as an acceptor and a domain pinning element. The effects of MnO2 observed in PZT-based normal ferroelectrics were also confirmed in PMN-based relaxor ferroelectrics. (C) 2001 Elsevier Science Ltd. All rights reserved.
