- Opis:
- This research was undertaken to determine whether by powder diffraction substitution in the "123"-type high T$\text{}_{c}$ oxides, Ln$\text{}_{1-x}$M$\text{}_{x}$Ba$\text{}_{2-y}$M$\text{}_{y}$Cu$\text{}_{3-z}$M$\text{}_{z}$O$\text{}_{6.5+δ}$ (where Ln = lanthanoid, M$\text{}_{x}$ = Me$\text{}^{3+}$, M$\text{}_{y}$ = Me$\text{}^{3+}$ and M$\text{}_{z}$ = Me$\text{}^{3+}$ and Me$\text{}^{2+}$) could be detected unequivocally. Numerous X-ray and a few neutron powder diffractograms were calculated for substituted compounds. Reflections most sensitive to substitution and the influence of site occupancy for Cu and O atoms are also characterized. The results are compared with some experimental data reported in the literature.
