Identification of a new type of electronic state in the magnetoresistive orthomanganites
PEROVSKITES of composition Ln1–xAxMnO3 (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 La2−xSrxCuO4. For small x, holes in the CuO2 sheets form non-adiabatic polarons ...

Physical and chemical properties of (Y1−xCax)(Ba2−xLax)Cu3O7−δ
The metallic conductivity of both the CuO2 sheets and the CuOx chains of YBa2Cu3O7−δ has been established. We have used double do** in (Y1−xCax)(Ba2−xLax)Cu3O7−δ to destroy the integrity of the CuO1−δ chains wh...
