Abstract

Element-specific x-ray magnetic circular dichroism measurements at the Ru L₃ absorption edge are used to search for the presence of a net Ru ferromagnetic moment in the superconducting state of RuSr₂Eu _1.5Ce_0.5Cu₂O₁₀. A net moment of 0.21 μB /Ru is observed in zero applied field. Together with a homogeneous Ru local structure probed by x-ray absorption fine-structure measurements, the results unequivocally demonstrate the coexistence of a ferromagnetic component in the magnetically ordered RuO₂ planes with superconductivity in the CuO₂ planes.
