Résumé

Structure, magnetic, and transport properties of La_0.7Sr _0.3 Mn_1-x Ti_xO₃ with x = 0, 0.1, 0.2, and 0.3 are studied. The system exhibits a rhombohedrally distorted perovskite structure. The structure refinement by Rietveld analysis of the X-ray powder diffraction data shows that the average distance (Mn, Ti)-O increases. The Curie temperature decreases when the titanium content increases. The Ti substitution also destroys the metallic state and the resistivity increases many orders of magnitude when the percentage of Ti increases.
