Ferroelectricity Driven by Twisting of Silicate Tetrahedral Chains
Hiroki Taniguchi, Akihide Kuwabara, Jungeun Kim +10
Conventional perovskite-type ferroelectrics are based on octahedral units of oxygen, and often comprise toxic Pb to achieve robust ferroelectricity. Here, we report the ferroelectr…

Integer spin-chain antiferromagnetism of the 4d oxide CaRuO3 with post-perovskite structure
Y. Shirako, H. Satsukawa, X. X. Wang +11
A quasi-one dimensional magnetism was discovered in the post-perovskite CaRuO3 (Ru4+: 4d4, Cmcm), which is iso-compositional with the perovskite CaRuO3 (Pbnm). An antiferromagnetic…
