Abstract: A model for explaining incommensurate spin modulation observed in La_2−x Sr_xCuO₄ is proposed without assuming stripe formation. In this model, all features of the observed spin textures in the entire doping range are associated only with the geometrical relations for the square lattice and with the competition between various forms of ordering of Sr ions.
