Fully filling-controlled pyrochlore ruthenates: emergent ferromagnetic-metal state and geometrical Hall effect

Carrier doping to the Mott insulator is essential to produce highly correlated metals with emergent properties. Pyrochlore ruthenates, Pr\(_{2}\)Ru\(_{2}\)O\(_{7}\) (Ru-\(4d\) electron number, \(n=4\)) and Ca\(_{2}\)Ru\(_{2}\)O\(_{7}\) (\(n=3\)), are a Mott insulator and a magnetic bad metal, respec...
