摘要：

The effects of double CuO2 layers in YBa2Cu3O6+x for 0<x<1 were studied critically. For x=0, the superexchange interaction through Y enhances the antiferromagnetic exchange interaction between the intralayer nearest-neighbor sites and the interlayer third-nearest neighbor sites. As a result, superconductivity due to Bose condensation of the molecular polarons proposed before is enhanced. An exciton-like excitation similar to that observed in SmB6 and YbB12 is observed to support the present model.
