摘要: Abstract We establish that Sr2RuO4 is extremely close to incommensurate spin density wave instability. With increasing Mn content, the RuO6 octahedron in unit cell varies. The of contracts along c-axis for x 0.20), and element shows +4 chemical valence (Mn4+). Spin-glass-related ferromagnetism enhancement observed x>0.20, which indicates critical ferromagnetic fluctuation due doping Sr2Ru1−xMnxO4.
