Abstract
Transition-metal oxides exhibit interesting properties which can be used for a variety of applications. The interactions between spin, charge and orbital degrees of freedom give rise to a rich phase of transition-metal oxides. Recently, the interface of heterostructure has been a hot topic in condensed matter physics. Here we present studies the magnetic transition of a LaMnO3-SrMnO3 superlattice by using resonant soft X-ray scattering. We used X-ray reflectivity and diffraction to characterize the LaMnO3-SrMnO3 superlattice. Resonant soft X-ray scattering with photon energy turned at the Mn L-edge (2p->3d) is sensitive to magnetic ordering. We report on experimental evidence for magnetic transition of the superlattice. Electronic properties at the interface resemble those of La1-xSrxMnO3 giving us a great opportunity to understand the colossal magnetoresistance (CMR) of manganite.
