An model of La<Subscript>2-x</Subscript>Sr<Subscript>x</Subscript>CuO<Subscript>4</Sub script> explaining the features of incommensurate spin textures without any assumption of stripe formation is proposed. The foundations of this model are the mechanism of negative-U center formation proposed earlier and the concept of specific ordering of doped ions. It is shown...<//sub></subscript></subscript></subscript>
