Abstract

The Mn K edge X-ray absorption near edge structure (XANES) of Pr0.67Sr0.33MnO3 films with different thicknesses on (001) LaAlO3 substrate was measured, and the effects of strain relaxation on film properties were investigated. The films showed in-plane compressive and out-of-plane tensile strains. Strain relaxation occurred with increasing film thickness, affecting both lattice constant and MnO6 octahedral rotation. In polarization dependent XANES measurements using in-plane (parallel) and out-of-plane (perpendicular) geometries, the different values of absorption resonance energy Er confirmed the film anisotropy. The values of Er along these two directions shifted towards each other with increasing film thickness. Correlating with X-ray diffraction (XRD) results it is suggested that the strain relaxation decreased the local anisotropy and corresponding probability of electronic charge transfer between Mn 3d and O 2p orbitals along the in-plane and out-of-plane directions. The XANES results were used to explain the film-thickness dependent magnetic and transport properties.

摘要

测量了在(001)LaAlO3衬底上不同厚度的Pr0.67Sr0.33MnO3薄膜的锰K边X射线吸收近边结构(XANES)，并研究了应变弛豫对薄膜性能的影响。薄膜表现出面内压缩应变和面外拉伸应变。应变弛豫随着薄膜厚度的增加而发生，影响晶格常数和MnO6八面体旋转。在使用面内(平行)和面外(垂直)几何结构的偏振相关XANES测量中，吸收共振能量Er的不同值证实了薄膜的各向异性。随着薄膜厚度的增加，这两个方向上的Er值相互靠近。结合X射线衍射(XRD)结果表明，应变弛豫降低了局部各向异性以及沿面内和面外方向Mn 3d和O 2p轨道之间电子电荷转移的相应概率。XANES结果被用于解释薄膜厚度依赖的磁性和输运性质。
