非晶稀土一过渡族(RE-TM)合金膜的很多特性引人注目,Gd-Co膜的磁单轴各向异性是其一.近年来,为探索这特性的来源,不少作者做了很多工作,其中大部份用Lorent_2显微镜观察膜的磁畴,研究易磁化轴的方向及它们随外界条件如氧含量,退火温度等困素的影响而变化的规律,同时用电镜的其他功能观察分析微观结构,用以与磁性联系.目前各向异性的机理尚不清楚,但看来膜中结构各向异性和应力各向异性与此
Much attention has been paid to the many properties of the amorphous rare earth-transitional (RE-TM) alloy film, and the magnetic uniaxial anisotropy of the Gd-Co film is one of them. In recent years, many authors have made explorations of the source of this property A lot of work, most of which use Lorent_2 microscope to observe the magnetic domain of the film, to study the direction of easy magnetization axis and their changes with the external conditions such as oxygen content, annealing temperature and other factors, while the other observation by electron microscopy Analysis of the microstructure for magnetic connection The mechanism of the current anisotropy is not known, but it appears that the structural anisotropy and stress anisotropy in the film are related to this
