We present an analysis of the long-wavelength spin-wave excitations in superlattices of diluted magnetic semiconductors. The different magnetic modes are classified as ‘‘pure-bulk,’’ ‘‘pure-interface,’’ and ‘‘bulk-interface’’ depending on whether they propagate along the axis of the superlattice in the two components of the structure, they decay in both regions, or they propagate in one and decay in the other. Numerical applications are considered related to inelastic light scattering from superlattices of Cd1-xMnxTe.

    Half-metallic ferromagnetism (HMFM) has great potential application in spin filter. However, it is extremely rare, especially in two-dimensional (2D) materials. At present, 2D materials have drawn international interest in spintronic devices. Here, we use ab initio density functional theory...
