Origin of high piezoelectric response of Pb(Zr_xTi_1-x)O_3 at the morphotropic phase boundary: Role of elastic instability
Akhilesh Kumar Singh, Sunil Kumar Mishra, Ragini +4
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-r…
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
Akhilesh Kumar Singh, Dhananjai Pandey, Songhak Yoon +2
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 si…
Evidence for monoclinic crystal structure and negative thermal expansion below magnetic transition temperature in Pb(Fe_1/2Nb_1/2)O_3
Satendra Pal Singh, Dhananjai Pandey, Songhak Yoon +2
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 re…
