Abstract

The magnetic properties of four different phases of the YBa 2 Cu 3 O x 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.
