This range includes the pseudocubic lattice parameters of most of the currently investigated complex oxides. The in-plane lattice parameter of strain-relaxed LASO films depends linearly on the composition, and these films grow with a smooth surface. On several different LASO-buffered substrates, ferromagnetic La0.7Sr0.3MnO3 (LSMO) films have been grown in predetermined strain states. A series of 30 nm thick LSMO films on LASO-buffered LaSrAlO4(001) demonstrates that continuously controlled coherent strains in a wide range, in this case from − 1 to +0.6%, can be obtained for the functional oxide films grown on LASO.application/pdfenghttps://creativecommons.org/licenses/by-nc-sa/3.0/530Buffered substratesCoherent strainComplex oxidesFunctional oxide filmsIn-plane lattice parametersLattice parametersLSMO filmsOxide substratesPseudocubicSmooth surfaceStrain stateStrain-relaxedTemplate filmsTunabilitiesWide-range strain tunability provided by epitaxial LaAl1−xScxO3 template filmsArticle
