Abstract
In this work, we have studied the crystal and magnetic structure of fully deoxygenated using neutron powder diffraction data. Rietveld profile refinement confirmed the presence of removable oxygen y within the Cu(1) layers. While for the fully oxygenated sample the space group describes the crystal structure adequately, for the deoxygenated sample the space group Cmcm was found to be more appropriate. Cmcm accounts for the disorder within the Cu(1) layers, which was also observed with Mössbauer spectroscopy. For the deoxygenated sample, magnetic peaks corresponding to three-dimensional antiferromagnetism were observed and were indexed with the propagation vector from 2 up to 300 K.
