Abstract

We have attempted a magnetostructural correlation for the oxocuprates: Y₂Cu₂O₅, BaCuO₂, Y ₂BaCuO₅, and YBa₂Cu₃O₆, all of which are closely related to the new high-T_c superconductors. It was found that this series of compounds has interesting combinations of ferro- and antiferromagnetic interactions as a consequence of the structural and electronic variety of copper. Y₂Cu₂O₅ and Y₂BaCuO₅ were shown to be chain and layer magnetic systems, respectively. BaCuO₂, a complicated 3D structure, has interesting effects of exchange interaction manifested in the temperature-dependent EPR spectrum. YBa₂Cu₃O₆ has been shown to possess a Néel point at 450 K from EPR intensity variation with temperature.
