Mn induced ferromagnetism spin fluctuation enhancement in Sr2Ru1−xMnxO4

We establish that Sr2RuO4 is extremely close to incommensurate spin density wave instability. With increasing Mn content, the RuO6 octahedron in the unit cell varies. The octahedron of RuO6 contracts along c-axis for x0.20), and Mn element shows the +4 chemical valence (Mn4+). Spin-glass-related fer...
