Raman effect in La2-xSrxCuO4
Ponosov Yu. S. , Bolotin G. A.
The symmetry of the Raman-active vibrations in a tetragonal La^ Sr017 Cu04 single crystal has been studied. A correlation is seen between the intensity of the Alg modes at 221 cm"1 and 431 cm"1 and the superconducting transition temperature.
