Nonreciprocal properties of magnetoplasmons in the imperfect magnetised semiconductor films sandwiched between the dielectric layers have been explored. It is demonstrated that losses qualitatively alter the eigenwave spectrum and the properties of magnetoplasmons. The effect of the structure parameters is analysed, and it is shown that strongly nonreciprocal attenuation of the eigenmodes in asymmetric structures may result in the unidirectional propagation of magnetoplasmonic modes. The competing effects of the reciprocal and nonreciprocal field displacement, and the impact of the field and power flux distributions on the mechanisms of nonreciprocal and unidirectional magnetoplasmon propagation in the imperfect semiconductor films are discussed.
