Structure refinement for La1.85Sr0.15Cu1-xNixO4 (x=0-0.19) transition-metal oxides

摘要

Polycrystalline La1.85Sr0.15Cu1-xNixO4 (0x0.19) solid solution with the K2NiF4 structure (S.G. I4/mmm) is a subject of structural investigation. Rietveld refinements performed for 16 samples provide a smooth linear or almost linear variation of lattice parameters, La(Sr) atomic coordinate and bond distances with Ni content. The z(O(2)) oxygen coordinate tends to be constant in the studied range. The present results are compared with previous data and discussed. Copyright (c) 2015 John Wiley & Sons, Ltd.
