Structure, magnetic, and transport properties of La0.7Sr0.3 Mn1−x TixO3 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. [Copyright &y& Elsevier]
