Abstract

Low temperature Weissenberg photograph of K₃D(SO₄)₂(-- 92\associated with the phase transition. Three type superlattice reflectionswere found below T_c (77.5, K), ones at(0 {1em}± 1/2 {1em}± 1/2) V-point and others atlattice points (Z and Γ-points) violating the extinctionrule of the space group A2/a of the high temperature phase. Thediffuse scattering was observed above T_c around(0 {1em}1/2 {1em}1/2) type reflection. It was revealedthat the double q condensation occurred at the V-point and ones atthe Z and Γ-points were secondary order parameters. Theunit cell of the low temperature phase was determined asa× 2b× 2c, and the space group was A2.
