Abstract

We report an inelastic light scattering study of double perovskite structure Sr₂Y(Ru_1-xCu_x)O₆ systems as a function of temperature and doping (x = 0.0, 0.05, and 0.1). As the temperature is lowered, for x = 0.0, the 767 cm^-1 A_1g apical oxygen phonon mode exhibits a softening and an enhancement of the linewidth in the antiferromagnetic phase. Similar anomalies are also observed for x = 0.1 when the superconducting gap opens. This suggests that a strong lattice-spin-charge coupling plays an important role in the magnetic and superconducting properties observed in these materials.
