|Title:||Phase transformation in unpoled bulk Pb (Zn13 Nb23) O3 -8%PbTi O3 single crystals revealed by the fracturing technique||Authors:||Chang, W.S.
|Issue Date:||2008||Citation:||Chang, W.S., Lim, L.C., Wang, F.-T., Tu, C.-S., Yang, P. (2008). Phase transformation in unpoled bulk Pb (Zn13 Nb23) O3 -8%PbTi O3 single crystals revealed by the fracturing technique. Journal of Applied Physics 103 (7) : -. ScholarBank@NUS Repository. https://doi.org/10.1063/1.2903344||Abstract:||Polished-and-annealed surfaces of bulk Pb (Zn13 Nb23) O3 -PbTi O3 (PZN-PT) single crystals were covered with a deformed layer and, hence, were unsuitable for structural study by means of x-ray diffraction technique. In contrast, fractured surfaces of bulk single crystals were relatively strain-free giving rise to distinctive diffraction patterns. Using the fracturing technique and high-resolution synchrotron x-ray diffraction, the present work shows that unpoled (annealed) PZN-8%PT single crystal undergoes a (MC) -T-C transformation upon heating under zero field condition, where T and C are the tetragonal and cubic phases, respectively. The symbol (MC) indicates an "apparent" type- C monoclinic phase, which in fact may be a rhombohedral phase of complicated domain structures. © 2008 American Institute of Physics.||Source Title:||Journal of Applied Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/61098||ISSN:||00218979||DOI:||10.1063/1.2903344|
