Vibronic Phenomena At Localized-Itinerant and Mott-Hubbard Transitions

It is argued from the pressure dependence of the transport properties that the Mott-Hubbard transition in the AMO₃ perovskites is first-order with a dynamic phase segregation appearing in the metallic phase on th...

Localized to Itinerant Electronic Transitions in Perovskite-Related Structures

Experiments on several perovskite-related transition-metal oxides at the cross-over from localized to itinerant electronic behavior reveal strong electron coupling not only to static, but also to dynamic oxyge...

Identification of a new type of electronic state in the magnetoresistive orthomanganites

PEROVSKITES of composition Ln_1–xA_xMnO₃ (where Ln and A are rare-earth and alkaline-earth elements respectively) have become the focus of scientific and technological interest because of their extraordinary elect...

Non-adiabatic electron-lattice interactions in the copper-oxide superconductors

Transport measurements distinguish the superconductive phase from the parent antiferromagnetic and the overdoped metallic phases in La_2−xSr_xCuO₄. For small x, holes in the CuO₂ sheets form non-adiabatic polarons ...

Physical and chemical properties of (Y_1−xCa_x)(Ba_2−xLa_x)Cu₃O₇−δ

The metallic conductivity of both the CuO₂ sheets and the CuO_x chains of YBa₂Cu₃O_7−δ has been established. We have used double do** in (Y_1−xCa_x)(Ba_2−xLa_x)Cu₃O_7−δ to destroy the integrity of the CuO_1−δ chains wh...

The Copper Oxides As Guides to New Superconductors

The copper oxides provide not only a remarkably high critical temperature T_c, but also model systems for the study of this new phenomenon. The search for new materials must be guided not only by our understanding...
