Abstract

The phase transformation of α′-NaV₂O₅ has been studied by electron diffraction. It has been observed for the first time that two different types of diffuse scatterings exist; one appears slightly above T_c and the other appears already at room temperature. The former type of diffuse scattering locks into superlattice reflections at T_c. The superlattice reflections and the former type of diffuse scattering are explained by a long-period anti-phase-domain structure (LPAPDS) model and the fluctuation of its period.
