Influence of Pressure and Substitution of Copper by Transition Metals on High-Tc Superconductors

  • Jacek Kasperczyk


The discovery of high-temperature superconductors of the LaBaCuO and YBaCuO type [1,2] promoted searching for new microscopic mechanisms of superconductivity. A variety of models was proposed to explain the anomalous properties of this new family of superconductors. Some of them neglect totally the classical (BCS) pairing caused by the electron- phonon interaction and introduce a novel mechanism, e.g. exchange of excitons Cal or the RVB state [4]. Other models consider electron- phonon interaction associated with different effects, e.g. an enhancement of the phonon mode due to spin density wave [5] or develop the idea of vibronic modes [6].
