众所周知,La0.7Sr0.3MnO3(LSMO)薄膜异质结构的磁状态与晶格、自旋、轨道和电荷状态密切相关,因为这些影响甚至在晶胞水平上的电和磁输运性质。因此,了解材料在纳米尺度上的磁性对于开发新的应用非常重要。最近发展的电子磁圆二色性(EMCD)技术允许通过使用传输的电子来确定原子特定位点的磁性信息,然而,它的灵敏度不足以在许多弱磁性系统中定量获取磁性信息。在这里,我们利用动态衍射效应辅助EMCD技术,定量确定的自旋和轨道磁矩的LSMO/SrTiO 3薄膜的纳米尺度上使用透射电子显微镜。进一步优化了数据处理,以增强EMCD信号的强度。
It is well known that the magnetic state of the La0.7Sr0.3MnO3 (LSMO) thin-film heterostructure is strongly correlated with the lattice, spin, orbital, and charge states, since these influence the electric and magnetic transport properties even on the unit-cell level. Therefore, understanding the material's magnetic properties on the nanoscale is important for the development of novel applications. The recently developed electron magnetic-circular dichroism (EMCD) technique allows the determination of atomic site-specific magnetic information via the use of transmitted electrons; however, its sensitivity is not high enough to quantitatively acquire magnetic information in many weak magnetism systems. Here, we utilized a dynamical diffraction-effect assisted EMCD technique to quantitatively determine the spin and orbital magnetic moment of LSMO/SrTiO3 thin films on the nanometer scale using a transmission electron microscope. Further, data processing was optimized to enhance the intensity of the EMCD signa...
