  • The perovskite oxides, Sr1-xLaxTiO3, were synthesized at high-temperature and high-pressure. XRD measurement shows that the samples with x0.5 are in single phase and belong to cubic phase structure. Cell volume increase at beginning of x, then decrease at x=0.4. XPS analysis indicates that Ti ions are in mixed valence. The influence of valence state of Ti ions on the lattice parameters is discussed.
