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.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-09-07t12:57:06z no. of bitstreams: 1 easy axis reorientation and magneto-crystalline anisotropic resistance of tensile strained (ga,mn)as films.pdf: 850485 bytes, checksum: efae9880759effb5c72bb9d316ba8309 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-09-07t13:11:09z (gmt) no. of bitstreams: 1 easy axis reorientation and magneto-crystalline anisotropic resistance of tensile strained (ga,mn)as films.pdf: 850485 bytes, checksum: efae9880759effb5c72bb9d316ba8309 (md5); made available in dspace on 2010-09-07t13:11:09z (gmt). no. of bitstreams: 1 easy axis reorientation and magneto-crystalline anisotropic resistance of tensile strained (ga,mn)as films.pdf: 850485 bytes, checksum: efae9880759effb5c72bb9d316ba8309 (md5) previous issue date: 2010; 其它
