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-Tc 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.
