摘要：

Recently developed relaxor lead magnesium niobate-ferroelectric lead zirconate titanate single crystals exhibit large length extensional k(33) coupling, improved thermal stability, and a higher coercive field compared to morphotropic lead magnesium niobate-lead titanate single crystals. Experimental results and implications for sound projectors are presented and discussed in terms of the morphotropic phase boundary slope and width. Spontaneous polarizations derived from the calculated atom shifts in both crystals compared favorably with experimental values. (c) 2007 American Institute of Physics.
