Structural transition and possible pressure-induced superconductivity in a suboxide La${}_5$Pb${}_3$O

Jiaqiang Yan, David Singh, Bayram Saparov +5

Here we report a structural phase transition and its possible competition with superconductivity in the suboxide La${}_5$Pb${}_3$O. Upon cooling through $T_t$ = 225 K, La${}_5$Pb${}_3$O tr…
