P.; Isaac, I.; Dow, John D.淡江大學物理學系College Park: American Physical SocietyPhysical Review B (Condensed Matter and Materials Physics) 67(5), 054509(6 pages)Muon spin rotation measurements of Sr2Y(Ru1-uCuu)O6 (for u=0.1) reveal two distinct muon sites: one located in a SrO layer (which is superconducting at low temperatures) and the other in a Y(Ru1-uCuu)O4 layer (which is magnetically ordered at low temperatures). A precursor spin-glass state due to the Ru moments is detected in high fields (≈3.3 kOe) in Y(Ru1-uCuu)O4 layers, with a spin-glass temperature of TG=29.25K. The Y(Ru1-uCuu)O4 layers order ferromagnetically in the a-b planes at the Néel temperature, TN≈23K. This in-plane ferromagnetism alt
