Abstract

In the present work, we report structural characterization of the La0.5Sr1.5Ti0.5Cr0.5O4 and LaSr2TiCrO7 phases by Rietveld analysis using GSAS program. Both the phases crystallize with tetragonal unit cell in the space group I4/mmm. The selected bond distances, as determined from structural refinements, suggests that the octahedra in both the phases are distorted.
