摘要

We present optical reflectance and Raman-scattering studies of double perovskite structure Sr₂Y(Ru_1-xCu_x)O ₆ systems as a function of temperature and doping. The optical conductivities of all doping samples studied have the character of an insulator at low frequencies, showing only optical phonons in the far-infrared. As the temperature is lowered, the A₁ _g apical oxygen phonon mode exhibits a noticeable softening below magnetic ordered and superconducting transitions, indicative of a strong lattice-spin-charge coupling in these materials.
