High Temperature Superconductors as a Member of Transition Metal Oxides

  • Sadamichi Maekawa
Part of the Springer Series in Solid-State Sciences book series (SSSOL, volume 125)


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.

    Compound Z, Bi2Sr2(Gd1-xCex)Cu2O10 +y, shows a very lowT c.9) The number of holes so far doped in experiment10) is rather small(p≥0.1); we expect a higherT c at optimum doping, which can be consistent with our correlation. 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
