[001] HREM image and corresponding Fourier transformation pattern (upper part) compared with a schematic representation of the structure portion (lower part) of the incommensurately modulated KSm(MoO4)2. In the structure presentation, the A = (K1-xSmx) positions are shown as circles decorated by a grey colour gradation from lightest grey (x < 0.05) to darkest grey (x > 0.95). |
