Evolution of structure and magnetism across the metal-insulator transition in the pyrochlore iridate $($Nd${}_{1-x}$Ca${}_x{)}_2$Ir${}_2$O${}_7$

Zach Porter, Eli Zoghlin, Samuel Britner +6

We report on the evolution of the thermal metal-insulator transition in polycrystalline samples of Nd${}_2$Ir${}_2$O${}_7$ upon hole-doping via substitution of Ca${}^{2+}$ for Nd${}^{3+}$. C…
