Oxygen Exchange in Pr2NiO4+δ at High Temperature and Direct Formation of Pr4Ni3O10−x
TL;DR: In this paper, the stability of Pr2NiO4+δ under pure oxygen flow by in situ measurement of its weight versus T Above 850°C a fast oxidation is observed corresponding to the ex-solution of PrOy species and to the formation of metallic Pr4Ni3O10−x.

Effect of substitution of magnetic rare earths for La on the structure, electric transport and magnetic properties of La2SrFe2O7
TL;DR: The powder X-ray diffraction studies showed that these phases crystallize with tetragonal unit cell in the space group I 4/mmm as discussed by the authors. But the unit cell dimensions decrease with substitution of Nd, Gd, and Dy for La, with more pronounced change in c which is attributed to shrinkage of the interlayer distances.
