Abstract
We report a Raman scattering study of perovskite-type (La0.7Sr0.3MnO3)m/(SrTiO3)n multilayers, m and n being the thickness of individual layers. The observed Raman spectra for different n and m are discussed in the light of structural modifications, namely a tensile-strain-induced rhombohedral-to-orthorhombic phase transition in the La0.7Sr0.3MnO3-layers. The present work validates tensile strain as an important variable in thin films, which does not only allow to distort the perovskite structure within a crystallographic space group but can well induce a transition towards another space group and its related physical properties.
