WebOct 15, 2003 · The four strontium ruthenates can be considered as members of the Ruddelsdon-Popper series, Sr n+1 Ru n O 3n+1 (n=1, 2, 3 and ∞). The structure is composed of planes of corner sharing RuO 6 octahedra separated by SrO rock-salt layers. The number of RuO 6 planes between two adjacent rock-salt layers is determined by the number n. WebMay 17, 2024 · The pyrochlore ruthenates Pr 2 Ru 2 O 7 (Ru 4 d electron number n = 4) and Ca 2 Ru 2 O 7 (n = 3) are a Mott insulator and a magnetic bad metal, respectively, due to the strong electron correlation.
