Raman scattering of light in La2-xSrxCuO4
Description
Symmetry of Raman scattering of light (RSL) of active oscillations in the La1.83Sr0.17CuO4 tetragonal monocrystal as well as in ceramic samples with different content of strontium (x=0.05-0.4) is investigated. Intensity correlation of A-1-G-modes at 221 cm-1 and 431 cm -1 distances with the temperature of superconducting transition is detected. The 221 cm-1 line is observed only in the ZZ-spectrum. The 431 cm-1 high-frequency band indicating to the isotope shift is related to oxygen atom oscillations
