摘要
A ferroelectric monoclinic phase of space group Cm (MA type) has been discovered in 0.65 Pb(Mg1/3Nb2/3)O3-0.35 PbTiO3 by means of high-resolution synchrotron x-ray diffraction. It appears at room temperature in a single crystal previously poled under an electric field of 43 kV/cm applied along the pseudocubic [001] direction, in the region of the phase diagram around the morphotropic phase boundary between the rhombohedral (R3m) and the tetragonal (P4mm) phases. The monoclinic phase has lattice parameters a = 5.692 Å, b = 5.679 Å, c = 4.050 Å, and β = 90.15°, with the bm axis oriented along the pseudocubic [110] direction. It is similar to the monoclinic phase observed in PbZr1-xTixO3, but different from that recently found in Pb(Zn1/3Nb2/3)O3-PbTiO3, which is of space group Pm (M c type).
