摘要: Magnetic anisotropy and magnetization reversal phenomena are studied in Ga1−xMnxAs films grown on GaAs(001). From the azimuthal dependence of magneto-optical Kerr rotation magnetic linear dichroism, in-plane 〈100〉 directions unambiguously assigned as axes easy magnetization. The values cubic uniaxial anisotropies determined. Magnetization proceeds by noncoherent spin irreversible jumps formation 90° domains.
