High Pressure Cation Ordering in ScVO3, InVO3 and the Sc(1-x)LuxVO3 Solid Solution

Abstract: We propose an investigation of highly tilted AVO3 perovskites. These phases are only accessible under high pressure. We propose to follow the bixbyite to perovskite high-P phase transition at elevated temperatures and to explore potential high-P phases for InVO3. Cation disordered bixbyite phases provide access to cation ordered high-P phases with strained coordination environments. For example, extreme VO6 octahedral tilting causes long range magnetic ground state ordering in ScVO3. InVO3 has only been made as a bixbyite phase; however, at high-P a cation ordered perovskite similar to ScVO3 is expected. Ex-situ experiments have not led to an ordered InVO3 phase, we believe this is due either to not knowing the appropriate P-T combination for the ordering process, or that the transition is reversible. In-situ experiments are therefore required to explore the cation ordered phase of InVO3
