The temperature- and doping-induced variation of structural, magnetic, and transport properties has indicated unique switching of spin-charge-orbital states in the Mn-O sheets of single-layered manganite crystals, Nd1-xSr1+xMnO4. In the composition range of 0.75<×<0.9, the magnetic ordering with alternate straight ferromagnetic chains occurs below TNap;150 K in the orthorhombically distorted sheets which perhaps originate from the orbital ordering at 270 K. In the crystals with commensurate doping levels (x=2/3 and 3/4), additional superlattice spots are observed with the propagation vectors [δ, δ, 0] [δ≈(1 - x)/2], suggestive of the charge-orbital ordering with zig-zag ferromagnetic chains.
