Pressure-induced crystalline-amorphous transition in NaVO3 and its recrystallization

Abstract Pressure-induced amorphization has been the subject of intense study for the past few years because of its importance in materials science and solid state physics. We reported a crystalline-amorphous phase transition at c . 60 kbar in NaVO 3 [Shen et al., Phys. Rev. B 49 , 1433 (1994)], which is the lowest pressure found for such transitions in ionic crystals. Here we report on the details of the transitional region and the re-linking of the VO 4 chains upon heating.
