Abstract :
On the basis of Landau´s theory of symmetry changes at continuous phase transitions formulae are derived for two incommensurate helical spin structures which are symmetry-allowed in MnSe/ZnTe superlattices. One of them is proposed as a possible consequence of a magnetic neutron scattering experiment. These spin structures have different extinction coefficients in their cross-sections for magnetic scattering of neutrons
