摘 要：Till now a lot of unidentified 'room temperature superconductors', some times mocked as USO (unidentified superconducting object), have been reported with a claimed Tc between 200 to 300K.Here we report a ferroelectric behavior for CuO around room temperature as well as at lower temperatures. This experimental result shows that the ferroelectric property, together with the antiferromagnetic transition which occurs around 230K, may give the apparently "superconducting' evidence around room temperature.Therefore the fundamental ferroelectric and magnetic properties of CuO must be considered seriously in identifying a possible new superconductors.
