Serial title, monograph or event: | Materials | Volume: | 16 | Issue: | 13 | Abstract: | The 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 group Pnma, 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. | URI: | https://hdl.handle.net/10316/112375 | ISSN: | 1996-1944 | DOI: | 10.3390/ma16134553 | Rights: | openAccess |
