摘要：

We have synthesized a new phase of layered perovskite Sr2CaRu2Oy related to Sr3Ru2O7. The Ca-substitution weakens the antiferromagnetic correlations and reduces the magnetic transition temperature from 15 to 3 K. The antiferromagnetic correlation between Ru4+ spins in Sr2CaRu2Oy can be varied by adjusting the oxygen content y.
