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…
