Synthèse et caractérisation d'une série de titanates pérowskites isotypes de [CaCu3](Mn4)O12
TL;DR: A series of titanates with perovskite-like arrangements and isostructural with [CaCu3](Mn4)O12 have been synthesized as discussed by the authors, where the total charge of the A sites can be modified by substituting the Ca2+ cations with monovalent ones and the tetravalent manganese cations of the B sites by a mixture of (Ti4+ + M5+) in which M = Ta, Nb, Sb, or (2) by a combination of cations plus vacancies.

Structure prediction of ordered and disordered multiple octahedral cation perovskites using SPuDS.
TL;DR: Comparison with reported crystal structures shows that SPuDS is quite accurate at predicting distortions driven by octahedral tilting, and unit-cell pseudosymmetry in Sr- and Ca-containing double perovskites is examined.

Relativistic Calculation of Anomalous Scattering Factors for X Rays
Don T. Cromer,David A. Liberman +1 more
TL;DR: In this paper, relativistic calculations of the photoelectric cross section have been made and the integral for the principal contribution to Δf′ has been evaluated numerically without approximation to the form of the cross section-vs-energy curve, as has been done in previous calculations.
