Element-specific probe of Ru magnetism and local structuren in RuSr{sub 2}Eu{sub 1.5}Ce{sub 0.5}Cu{sub 2}O{sub 10}.

Journal Article · · Phys. Rev. B
Element-specific x-ray magnetic circular dichroism measurements at the Ru L{sub 3} absorption edge are used to search for the presence of a net Ru ferromagnetic moment in the superconducting state of RuSr{sub 2}Eu{sub 1.5}Ce{sub 0.5}Cu{sub 2}O{sub 10}. A net moment of 0.21 {micro}{sub B}/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 RuO{sub 2} planes with superconductivity in the CuO{sub 2} planes.
