The paper presents a mean-field model to describe hole-mediated ferromagnetism in zinc-blende and wurtzite diluted magnetic semiconductors. The model considers strong spin-orbit and $kp$ couplings in the valence band, the effect of strain on hole density-of-states, and the influence of disorder and carrier-carrier interactions. The model is applied to (Ga,Mn)As, where it successfully reproduces experimental results for Curie temperatures, easy axis directions, and anisotropy field magnitudes as a function of biaxial strain. It also explains the unusual sign, magnitude, and temperature dependence of magnetic circular dichroism. The study highlights the importance of $kp$ and spin-orbit interactions in controlling the Curie temperature, saturation magnetization, and magnetic anisotropy. The results provide insights into the physics of hole-mediated ferromagnetism in semiconductors and suggest potential directions for designing novel ferromagnetic semiconductor systems.The paper presents a mean-field model to describe hole-mediated ferromagnetism in zinc-blende and wurtzite diluted magnetic semiconductors.
