Abstract
We present a Raman scattering study of Ru(Sr,La)2GdCu2O8, a material that exhibits coexisting magnetic order and high-temperature superconductivity for x=0, but becomes semiconducting for x=0.1. A pronounced anomaly of an oxygen vibration at the magnetic transition temperature evolves smoothly through the superconductor-semiconductor transition. In contrast, a previously observed, broad low-energy mode disappears rapidly with increasing x, mirroring the rapid hole-concentration dependence of the net magnetization in the magnetically ordered state. We discuss these findings as possible indications of spin, charge, and orbital order of the Ru ions.
