Abstract

Specific splitting of the l/3(hkl) reflections along with the B2(CsCl)-matrix reflections at the B2↔IC↔C(R) transition at T≤T_R^cor was observed. Linear size of the R-phase needle-like domain structure λ₁ correlates well in a reverse manner with degree of incommensurability δ₁. The CDWs formation with coupling to longitudinal displacement wave is thought to be responsible for the B2↔R phase transition.
