HighlightsOrthorhombic Eu1−xYxMnO3(0.0 ≤x≤ 0.5) thin films were successfully synthesized by spin-coating.The film phase evidences an additional contribution to lattice strain with increasing Y-content.Appreciable modification of magnetic response from bulks to films due to structural distortions.AbstractThe effects on the structure and magnetic properties of Eu1−xYxMnO3(0.0 ≤ x ≤ 0.5) thin films due to lattice strain were investigated and compared with those obtained in equivalent composition ceramics. The films were deposited by spin-coating chemical solution onto Pt\TiO2\SiO2\Si (100) standard substrates. X-ray diffraction and Raman spectroscopy measurements revealed that all films crystallize in orthorhombic structure with space groupPnma, observing an added contraction of the unit cell with increasing Y-substitution ou Eu, corresponding to a broadening of the Mn-O1-Mn angle and a gradual decrease in magnetic order response.
