Abstract

This work presents structure, thermodynamic, magnetic and electric measurements performed on pure sintered CuO. Beside the known properties of CuO we observed anomalous thermodynamic, magnetic and electric behaviour in the temperature range between 230 K and 190 K strongly dependent on the story of the sample. A possible explanation of these effects could arise from Jahn-Teller dynamic distortions of the CuO6 bipyramidal structure that can be considerably influenced by the oxygen vacancies. Since these effects seem to be correlated with the superconducting properties observed in cuprate systems, further and more detailed experiments are in progress. © 1988.
