The ruthocuprates include samples that are both weak ferromagnets and superconductors for part of the phase diagram. The results indicate that adding hydrogen changes the many-body response on the CuO2 planes. The results further indicate that ferromagnetic order alters the core level states. We discuss implications of these data.X-RAY-ABSORPTIONELECTRONIC-STRUCTURESUPERCONDUCTIVITYCOEXISTENCEMAGNETISMSRRUO3YBA2CU3O7-DELTAFERROMAGNETISMRUSR2GDCU2O8TRANSITIONtext::journal::journal article::research article
