Resumen:
We report structural, magnetic and transport measurements on La0.6Sr0.4MnO3thin "TiSrOlms grown on MgO and TiSrO3
substrates with thickness varying from 5 to 500 nm. We found that the lattice mismatch between substrates and
fillms affects the morphology and induced-strains of the fillms. We show that these two di!erent e!ects strongly infuence
