Simultaneous collapse of antiferroquadrupolar order and superconductivity in PrIr${}_2$Zn${}_{20}$ by nonhydrostatic pressure

Kazunori Umeo, Riho Takikawa, Takahiro Onimaru +3

Superconductivity in PrIr${}_2$Zn${}_{20}$ appears at $T_{\mathrm{c}}=0.05$ K in the presence of an antiferroquadrupolar order below $T_{\mathrm{Q}}=0.11$ K. We have studied pressure depen…
