Anomalous lattice contraction and emergent electronic phases in Bi-doped Eu${}_2$Ir${}_2$O${}_7$

Prachi Telang, Kshiti Mishra, Giacomo Prando +2

We study the pyrochlore series (Eu${}_{1-x}$Bi${}_x$)${}_2$Ir${}_2$O${}_7$ for $0\le x\le 1$. We show that for small $x$, the lattice undergoes an anomalous contraction but the all-in/a…
