Structural Evolution, Defect Chemistry, and Microstructural Tuning of Novel La2-xCaxMn2-yCoyO6-δ Double Perovskite Oxides Synthesized via Facile Sol–Gel Route
Lanthanum-based double perovskite oxides (DPOs) have attracted considerable attention owing to their structural tunability, defect chemistry, and redox-active transition-metal centers, making them promising candidates for energy-related applications. In the present study, a series of novel La2-xCaxMn2-yCoyO6-δ (x = y =...
