We establish that Sr2RuO4 is extremely close to incommensurate spin density wave instability. With increasing Mn content, the Ru06 octahedron in the unit cell varies. The octahedron of RuO6 contracts along c-axis for x <020, Mn element mainly showing the +3 chemical valence (Mn3), and it expands along c-axis with further increasing Mn content (x> 020), and Mn element shows the +4 chemical valence (Mn4). Spin-glass-related ferromagnetism enhancement is observed for x> 020, which indicates the critical ferromagnetic spin fluctuation due to Mn doping in Sr2Rui-MnO4.
