| 英文摘要 | We present a study of magnetic anisotropy by using magneto-transport and direct magnetization measurements on tensile strained (ga,mn)as films. the magnetic easy axis of the films is in-plane at low temperatures, while the easy axis flips to out-of-plane when temperature is raised or hole concentration is increased. this easy axis reorientation is explained qualitatively in a simple physical picture by zeners pd model. in addition, the magneto-crystalline anisotropic resistance was also investigated experimentally and theoretically based on the single magnetic domain model. the dependence of sheet resistance on the angle between the magnetic field and [1 0 0] direction was measured. it is found that the magnetization vector m in the single-domain state deviates from the external magnetic field h direction at low magnetic field, while for high magnetic field, m continuously moves following the field direction, which leads to different resistivity function behaviors.
