摘要：

Long range antiferromagnetic order is observed below TN ≈ 13 K for Y2Cu2O5. The magnetic structure consists of quasi-two-dimensional ferromagnetic layers coupled antiferromagnetically. The magnetic moment is characteristic of S = 1 2 without quantum fluctuation effect as in 2D antiferromagnets related to high temperature superconductors. It is inferred that the fundamental difference with the related superconducting systems is the in-plane ferromagnetic interactions. © 1990.
