抄録

Electronic Raman scattering spectra for cuprate superconductors, La2-xSrxCuO4, and prototypical strongly correlated metals, Sr1-xLaxTiO3, were investigated and compared with each other. All the spectra can be reproduced by "extended" relaxational function with ω-dependent Γ. Electron correlation effect leads to strong ω dependence of Γ, which produces the spectral weight of χ″(ω) up to the high energy region. We also found anomalous symmetry dependence of the spectral intensity for La2-xSrxCuO4 in the lightly doped region.
