We report on high-pressure $p \leq 45$ GPa resistivity measurements on the perovskite-related mixed-valent compound CsAuBr$_3$. 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; above $p = 14$ GPa a semiconducting state is observed. From this pressure up to the highest pressure of $p… ## Figures from this paper ## References SHOWING 1-10 OF 50 REFERENCES • Geology • 1970 Resistivity and lattice-constant measurements under high pressure on SmS show that a$4f\ensuremath{\rightarrow}5d\$ electronic transition in SmS occurs discontinuously at 6.5 kbar at room
