Title: | JAHN-TELLER EFFECT IN THE LA-SR-CU-O SUPERCONDUCTOR |
Authors: | CASTRO, JJ SALCIDO, A RamosGOMEZ, F Yépez, E Calles, A Cabrera, A |
Issue Date: | 1991 |
Abstract: | The CuO6 octahedron in the T structure of the La - Sr - Cu - O superconductor is considered within the quasi-molecular approximation in order to calculate the electronic structure and the vibrational modes that could participate in the Jahn-Teller effect. The electronic calculations are made within the extended Huckel model and the vibrations are taken from previously reported results. Once the electronic and vibrational participants are determined using group theory analysis, the intensity of the electron-phonon interaction is calculated to establish the Jahn-Teller deformation. |
