摘要/Abstract

摘要： Effect of structure parameter n and its coupling with the connection mode among RuO₆ octahedra of Sr_n+1Ru_nO_3n+1 (n=1, 2, ∞) are investigated. The gradually enhanced rotation and tilting effect with increasing n are observed in Sr_n+1Ru_nO_3n+1. Besides, the chemical valence of Ru is not changed, while the one of Sr gradually varies with increasing n, which highlights the great contribution of connection mode to the chemical environment. Our results show a strong n dependence on the connection mode between octahedra in Sr_n+1Ru_nO_3n+1 (n=1, 2, ∞).
