It is shown that a presence of small amount of nanometer size MnAs clusters in (Ga,Mn)As thin films can enhance the coercivity by factors up to ∼100 without significantly degrading the Curie temperature or saturation magnetization. This approach to controlling the coercivity while maintaining high Curie temperature, may be important for realizing ferromagnetic semiconductor-based devices.
