利用软x射线磁性圆二色(XMCD)吸收谱测得Fe/MgO膜不同磁化方向的轨道磁矩和自旋磁矩.实验表明,沿铁单晶薄膜的不同方向,铁原子轨道磁矩的改变量达到600%以上,而自旋磁矩的变化约50%,但原子的总磁矩没有如此大的改变.结合常规方法分析了铁薄膜的宏观磁各向异性性质,半定量地获得磁矩与宏观各向异性能的关系,并对样品的磁矩和磁各向异性能进行了比较. The orbital and spin magnetic moments of different magnetization directions of Fe / MgO films were measured by soft X-ray magnetic circular dichroism (XMCD) absorption spectra. The experimental results show that the magnetic moment of iron orbital The amount of change is more than 600%, and the change of spin magnetic moment is about 50%, but the total magnetic moment of the atom is not changed so much.According to the conventional method, the macro-magnetic anisotropy property of the iron thin film is analyzed, Moment and macro anisotropy energy, and the magnetic moment and magnetic anisotropy of the samples were compared.
