摘要: Orbital ordering has been less investigated in epitaxial thin films, due to the difficulty evidence directly occurrence of this phenomenon film samples. Atomic resolution electron microscopy enabled us observe structural details ultrathin LaVO3 films. The transition orbital layers as ≈4 nm was probed by temperature-dependent Raman scattering spectroscopy multilayer From and temperature dependence 700 cm–1 active mode it can be inferred that phase associated with takes place films at about 130 K.
