Abstract
A systematic study of (La,Pr,Nd,Sm)1-xSrxTMO3 (TM = Co, Fe, Mn; x ≤ 0.5) perovskites with a high-entropy A-site configuration is performed to evaluate the influence of configurational entropy on their structural and functional properties. The observed phase structures and phase transitions closely follow those of the corresponding La-based analogs, indicating that the introduction of multiple rare-earth cations does not significantly alter the crystallographic behavior. Similarly, the thermal expansion coefficients remain comparable to those reported for conventional La- and Nd-based perovskites, with minor anomalies that can be rationalized in terms of previously identified lanthanide–transition metal interactions. The electrical conductivity exhibits behavior closely resembling that of Nd-based perovskites, which is consistent with the effective average ionic radius of the mixed A-site cations. Overall, the influence of the high-entropy A-site configuration on the investigated properties is limited, and only rare deviations from classical rule‑of‑mixtures predictions are observed. Importantly, this demonstrates that high-entropy perovskites can serve as direct replacements for conventional compositions in most applications without compromising performance, while retaining the previously identified potential benefits associated with configurational disorder, such as enhanced long-term stability in SOFC applications or modified magnetic behavior.
