用正μ子自旋弛豫方法（μ+SR）研究了YBa_2Cu_3Ox系统的四种不同相的磁性，其中包括著名的90 K超导体.发现缺氧的四元绝缘相（x = 6.2）在室温附近是磁性有序的，因此很可能是反铁磁性的。
The magnetic properties of four different phases of the YBa2Cu3Ox system, including the famous 90 K superconductor, have been probed by the positive muon spin relaxation method (µ+SR). The oxygen-deficient tetragonal insulating phase (x∼6.2) was found to be magnetically ordered, thus most likely antiferromagnetic, near room temperature.
