Part II: Second generation wavelets, structure and the perovskite structure, present various electron transport properties leading to semiconducting, metallic or superconducting behavior. These properties are due to copper, which exhibits a mixed valence in these oxides that seems to be enhanced by the localization of copper in the pe

Part II: Second generation wavelets,perties of the La. CuO. - and YBa. Cu. O. -type structural families. It is, of course, not possible to discuss here all these results, in spite of their great importance from the physical viewpoint. It should, however, be emphasized that it is very difficult to interpret many of these papers, in spi

Part II: Second generation wavelets,, even when the lanthanide is a magnetic cation, has encouraged the investigation of the related quaternary oxides involving copper, an alkaline earth element and a trivalent element other than a rare earth. Two families were discovered successively: the bismuth copper oxides and the thallium copper

Introduction to continuous wavelet analysis,cribed in Chaps.2 and 5 that generate the high-T. superconductor structures. They are known by solid-state chemists to favor nonstoichiometric features. The phenomena thus generated often play a prominent role in the material properties and there are numerous examples that illustrate their influence

The factors that may generate defects in the oxygen framework are numerous and have several origins, including oxygen content, size of the grain, nature of the precursors and thermal treatments. They can result either in strong inhomogeneities, for the most stoichiometric YBa.Cu.O. su

Although the relationship between the crystal chemistry of these materials and their superconducting properties is so far not understood, we would like to discuss
