利用X射线磁性圆二色技术对Co0.9Fe0.1薄膜面内元素分辨的磁各向异性进行了研究,通过剩磁模式测量不同磁化方向的样品组分原子单位空穴磁矩的变化,发现除了在生长的磁诱导方向存在易磁化轴外,在与该轴垂直的方向还存在一个类似易轴的软磁化轴;面内的两个难磁化轴与易磁化轴取向大约成66°夹角,从而构成了面内双轴磁各向异性;对不同组分元素,其单位空穴磁矩随磁化方向的变化趋势基本相同,不同磁化方向Fe原子单位空穴的磁矩值约为Co的对应值的87%,反映了Fe原子和Co原子之间存在着强烈的铁磁性耦合.
The magnetic anisotropy of the element in the Co0.9Fe0.1 thin film was studied by X-ray magnetic circular dichroism. The variation of the magnetic moments of the hole elements in the sample components with different magnetization directions was measured by the residual magnetization mode. In addition to the presence of an easy axis of magnetization in the magnetically induced growth direction, there is an axis of soft magnetization similar to the axis in the direction perpendicular to the axis; the two in-plane magnetization axes are approximately 66 ° from the axis of easy axis alignment , Which constitutes the in-plane biaxial magnetic anisotropy. For different elements, the unit magnetic moment of the unit hole changes with the magnetization direction basically the same, and the magnetic moment of the unit hole of Fe atomic unit in different magnetization directions is about Co 87% of the corresponding value reflects the strong ferromagnetic coupling between Fe atoms and Co atoms.
