Abstract
We report on high-pressure p≤45 GPa resistivity measurements on the perovskite-related mixed-valent compound CsAuBr3. The compounds high-pressure resistivity can be classified into three regions: For low pressures (p<10 GPa) an insulator to metal transition is observed; between p=10 GPa and 14 GPa the room temperature resistivity goes through a minimum and increases again; and above p=14 GPa a semiconducting state is observed. From this pressure up to the highest pressure of p=45 GPa reached in this experiment, the room-temperature re
