Abstract
The paper presents a theoretical analysis of magnetization waves in a diluted magnetic semiconductor. Using the continuous medium approximation, we derived a dynamical equation system that describes the magnetization evolution of the paramagnetic matrix and magnetic admixture ions. Two possible solutions were considered. The first involved a travelling wave of finite amplitude, which was stable in the system with a ferromagnetic coupling with admixture ions. The second solution involved a solitary wave. Here, the soliton amplitude and velocity were determined by the interaction between the admixture ions themselves and between them and the base matrix. The dipolar coupling of the matrix and admixture had significant influence on the wave stability.
