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, (formula presented) In the composition range of (formula presented) the magnetic ordering with alternate straight ferromagnetic chains occurs below (formula presented) in the orthorhombically distorted sheets which perhaps originate from the orbital ordering at 270 K. In the crystals with commensurate doping levels (formula presented) and (formula presented) additional superlattice spots are observed with the propagation vectors [Δ, Δ, 0] (formula presented) suggestive of the charge-orbital ordering with zig-zag ferromagnetic chains.
