Ultralow-temperature thermal conductivity of Pr2Ir2O7: a metallic spin-liquid candidate with quantum criticality

J. M. Ni, Y. Y. Huang, E. J. Cheng +6

The frustrated pyrochlore iridate Pr${}_2$Ir${}_2$O${}_7$ was proposed as a metallic quantum spin liquid located at a zero-field quantum critical point. Here we present the ultralow-temp…
