摘要: Magnetic anisotropies of ferromagnetic thin films are induced by epitaxial strain from the substrate via strain-induced anisotropy in orbital magnetic moment and that spatial distribution spin-polarized electrons. However, preferential occupation metallic La$_{1-x}$Sr$_x$MnO$_3$ (LSMO) studied x-ray linear dichroism (XLD) has always been found out-of-plane for both tensile compressive hence irrespective anisotropy. In order to resolve this mystery, we directly probed electrons LSMO under angle-dependent circular (XMCD). Anisotropy spin-density was be in-plane strain, consistent with observed The ubiquitous seen XLD is attributed spin-up spin-down orbitals surface dead layer.
