| 中文摘要 | Incommensurate modulation structure in uniaxial relaxor ferroelectric Ca0.28Ba0.72Nb2O6 single crystals was investigated using transmission electron microscopy (TEM). The wave-modulation vector can be expressed as q=(1/2)c(*)+(1+delta)(a(*)-b(*))/4, where the incommensurability parameter delta was determined to be about 0.09 from [110] diffraction pattern. High-resolution TEM observations along [110] zone provided direct evidence of the incommensurate superstructure. Structural modulation was also evident by high-resolution TEM images through [001] zone, where a sinusoidal variation along [110] and [1(1) over bar 0] was identified. The incommensurate superlattice structure is caused by the uniform mixing of slabs of two orthorhombic cells. |
