Etude de la phase non commensurable de { N(CH3)4 } 2 ZnCl4 par Laüe monochromatique
Year: 1980
Type: article
Abstract: A monochromatic Laüe method is applied to the determination of the parameter δ characteristic of the satellites positions (wave vector qδ = (1 - δ)/3 a*) in the incommensurate phase of { N(CH 3)4 }2ZnCl4. Although the ferroelectric phase is very similar to that of K2SeO4, K2ZnCl 4 and Rb2ZnCl4, the parameter δ in the incommensurate phase of { N(CH3)4 }2ZnCl4 drastically differs from that measured in the three others compounds (by the absolute value and sign : - 0.32 compared to 0.06, 0.09 and 0.09 at Ti ). A brief discussion on the diffuse scattering observed in the paraelectric phase (Pnma) is presented too.
