Abstract
The present work reports a systematic and accurate study on crystal structu re and chemical homogeneity of underdoped La2-xMxCuO4 (M = Ba, Sr). Samples ' structural characterization performed by Rietveld refinement of XRD powde r diffraction profiles provided an accurate working trendline for the dopan t concentration determination. Furthermore FT-IR skeletal analysis and SIMS investigations ensured chemical homogeneity even for samples with very low dopant contents.
