Investigation of crystal structure of SrLa(FeTi)O6 and BaLa(FeTi)O6 perovskites by Rietveld Refinement at room temperature.
- •
Structural analysis rules out the cubic structure with space grop Fm
m for BaLa(FeTi)O6 and tetragonal structure with space group Pnma for BaLa(FeTi)O6 as reported by earlier authors.- •
We have reported the cubic structure with space group Pm
m for BaLa(FeTi)O6 and orthorhombic structure with space group Pnma for SrLa(FeTi)O6.
