Abstract
Theory of hole magnetization ${M}_{c}$ in zinc-blende diluted ferromagnetic semiconductors is developed relaxing the spherical approximation of earlier approaches. The theory is employed to determine ${M}_{c}$ for $(\mathrm{Ga},\mathrm{Mn})\mathrm{As}$ over a wide range of hole concentrations and a number of crystallographic orientations of Mn magnetization. It is found that anisotropy of ${M}_{c}$ is practically negligible but the obtained magnitude of ${M}_{c}$ is significantly greater than that determined in the spherical approximation. Its sign and value compares favorably with the results of available magnetization measurements and ferromagnetic resonance studies.
