The XRD pattern of BaTiO3 particles, which were synthesized under irradiation of ultrasonic sound for 0.5 h, showed sharp diffraction peaks that corresponded to the cubic BaTiO3 phase. Only a small amount of BaCO3 contamination was present in the sample. The Raman active modes of the ...

X-ray diffraction (XRD) patterns in Figure 1 show that the nanowires are composed of highly crystalline, cubic per- ovskite structure of BaTiO 3 (pattern a) and SrTiO 3 (pat- tern b). The unit-cell parameters for BaTiO 3 and SrTiO ...
摘要 采用溶胶⁃凝胶与固相反应相结合的方法制备了x NiFe 2O 4/(1-x )BaTiO 3(x =0.1,0.2,0.3,0.4,0.5,0.6)系列复合多铁材料.X 射线衍射(XRD)结果表明,复合材料中只含有钙钛矿结构的BaTiO 3和尖晶石结 构的NiFe 2O 4,说明共烧过程中两者未发生明显的化学反应,铁电相与铁磁相共存.扫描电子...
(XRD) measurements with a Cu Kα1source (Supplementary Fig.4). From reciprocal space maps of the BTO film around the PSO{(33\bar{2})}_{{{\rm{O}}}and PSO{(240)}_{{{\rm{O}}}reflections, we concluded that the BTO films are fully coherent with the PSO substrate. The lattice...
