High Temperature Superconductors as a Member of Transition Metal Oxides
Many transition metal oxides have perovskite-type crystal structure. In manganites with this structure, the orbital degeneracy of 3d electrons in Mn ions brings about the characteristic properties including ferromagnetism. Relation between crystal structure and electronic structure in the cuprates is examined in the ionic model. Then, the relation between electronic structure and high temperature suoerconductivity is examined in the cluster model approach.

The experiment also suggests a valley inT c versusp curve, which may be another reason of the lowT c. Further experimental works are desired.Google Scholar
