摘要
The present work reports a systematic and accurate study on crystal structure and chemical homogeneity of underdoped La2-xMxCuO4 (M = Ba, Sr). Samples' structural characterization performed by Rietveld refinement of XRD powder diffraction profiles provided an accurate working trendline for the dopant concentration determination. Furthermore FT-IR skeletal analysis and SIMS investigations ensured chemical homogeneity even for samples with very low dopant contents.
