The combined effects of applied electric field and axial compressive stress on the strain behavior of [011]-poled Pb(Mg1/3Nb2/3)O3–(28–32)%PbTiO3 [PMN-(28–32)%PT] single crystals of [011]-length cut have been investigated. For this crystal cut, the axial compressive stress has little effect on the R-O transformation field, the latter being >1.0 kV/mm for PMN-(28–30)%PT. This crystal cut is thus ideal for applications involving large electric field and axial compressive stress.
