Epitaxial La_{0.67}Sr_{0.33}MnO_{3} thin films with a significant increased temperature of metal-insulator transition (~450 K) are prepared on single crystal MgO (001) substrates using different deposition techniques - a dc magnetron sputtering or a pulsed laser deposition. The crystalline perfection of the films is characterized by X-ray diffraction technique (rocking curve measurements and reciprocal space maps). As a consequence of different methods of the film preparation we show various types of the LSMO crystal structure. Our results indicate that all the LSMO layers grown on the MgO substrate with a lattice misfit of about 8% are relaxed.
