摘要：

A magnetic susceptibility which decreases with decreasing temperature is observed in all CuO2 based superconductors with less than optimal doping. We propose that in La2-xSrxCuO4 this is due to spin density wave ordering which is prevented by the low spatial dimensionality, while in YBa2Cu3O6.6 it is due to the interplay between antiferromagnetic fluctuations within a plane and singlet pairing of electrons between nearest neighbor planes.
