| Summary: | <p><em> A superconducting pair in high-temperature superconductivity structure was supposed to have an electrical quadrupole moment. It was shown, that under certain conditions, at the part of acoustic phonons, conduction electrons in high-temperature superconductivity structure can form superconducting pairs, when the interaction energy of the quadrupole moment of a superconducting pair with the structure electric field exceeds the energy of Coulomb repulsion between electrons. The electrical field parameters in a CuO<sub>2</sub> plane of high-temperature superconductivity structure have been obtained by the method of effective point charges. The distance between electrons in superconducting pair in a CuO<sub>2</sub> plane have been estimated in ~ 75 ÷ 130 Å. Within the framework of the suggested model it was shown that high-temperature superconductivity IR-spectra, which were observed at 500 cm<sup>-1</sup>, can be caused by the quadrupole resonance of superconducting pairs.</em></p> |
