Temperature dependent structural changes in a nearly pure monoclinic phase composition (x=0.525) of Pb(Zr_xTi_1-x)O_3 (PZT) have been investigated using Rietveld analysis of high-resolution...

High-resolution synchrotron XRD study of Zr-rich compositions of Pb(Zr_xTi_1-x)O_3 (0.525\leq x \leq 0.60): evidence for the absence of the rhombohedral phase (2008)

Singh, Akhilesh Kumar, Pandey, Dhananjai, Yoon, Songhak, Baik, Sunggi, Shin, Namsoo

Results of Rietveld analysis of the synchrotron XRD data on Pb(Zr_xTi_1-x)O_3 (PZT) for 0.525\leqx\leq0.60 are presented to show the absence of rhombohedral phase on the Zr-rich side of the...

Evidence for monoclinic crystal structure and negative thermal expansion below magnetic transition temperature in Pb(Fe_1/2Nb_1/2)O_3 (2007)

Singh, Satendra Pal, Pandey, Dhananjai, Yoon, Songhak, Baik, Sunggi, Shin, Namsoo

The existing controversy about the room temperature structure of multiferroic Pb(Fe_1/2Nb_1/2)O_3 is settled using synchrotron powder x-ray diffraction data. Results of Rietveld refinements in the...
