- 論文の詳細を見る
The I-II phase transition of betaine phosphate crystal associated with the ordering of PO_4 groups has been studied by X-ray scattering : The observations are concerned on (1) the temperature dependence of lattice constants, (2) the temperature dependence of the order parameter of PO_4 which followed the relation η ∝ (T_c - T)^β, β=0.42(1), and (3) the anisotropic distribution of critical diffuse scattering in the reciprocal space above Tc ; clongated along the c-direction, shortened along the b-direction. The critical X-ray diffuse scattering has been analyzed. The correlation lengths along three principal directions of anisotropic scattering distribution were estimated. The temperature dependence of the correlation length and staggered susceptibility were discussed.
