Abstract
Incommensurate structures in uniaxial magnetic ferroelectrics are theo retically investigated. Two different phases called ''easy-axis like'' and ''easy-plane like'' have been found. The transition between them is compared with the ''spin-flop'' in antiferromagnets. The critical f ield is obtained. The second derivative of the susceptibility with res pect to the magnetic field is shown to have the jump at the critical f ield. The effect of higher order anisotropy is discussed.
