Influence of the Cationic Distribution of the B-Site of La(MnFeCoNiCu)O3-δ High-Entropy Oxides on the Crystal Structure and Properties

Abstract

High-entropy perovskites La(MnFeCoNiCu)O3–δ are obtained via combustion of glyc-erol-nitrate precursors and consequent annealing at 1100 °C. Most of the samples are single-phase with different symmetric types within the perovskite-like crystal structure. The cationic distribution over sintered sample
