Phys. Rev. B 71, 134110 (2005) [10 pages]Low-temperature phases in PbZr0.52Ti0.48O3: A neutron powder diffraction studyReceived 21 July 2004; revised 21 December 2004; published 29 April 2005 A neutron powder diffraction study has been carried out on PbZr0.52Ti0.48O3 in order to resolve an ongoing controversy about the nature of the low-temperature structure of this strongly piezoelectric and technologically important material. The results of a detailed and systematic Rietveld analysis at 20 K are consistent with the coexistence of two monoclinic phases having space groups Cm and Ic, respectively, in the approximate ratio 4:1, and thus support the findings of a recent electron diffraction study by Noheda et al. Phys. Rev. B 66 060103 (2002). The results are compared to those of two recent conflicting neutron powder diffraction studies of materials of the same nominal composition by Hatch et al. Phys. Rev. B 65 212101 (2002) and Frantti et al. Phys. Rev. B 66 064108 (2002). © 2005 The American Physical Society URL:
