Popis: The electron pairing mechanism for superconductivity in cuprates is generally attributed to magnetic interactions because superconductivity occurs on the verge of frustrated low-dimensional antiferromagnetic order in Cu–O planes or chains. CuO is the simplest copper oxide that may be the fundamental one not just because till now only compounds containing the Cu–O–Cu bond have produced the high- T c superconductivity but also because recently we found that charge stripes exist in this simplest compound. Here we report strong charge–spin–orbital coupling in CuO, which shows that CuO is a reference system for studying the electron correlation in cuprates.
