Effective Tuning of Electromagnetic Properties in Sr0.9Y0.1FeO3-δ Ceramics via Higher Valence and Spin Mn Doping at the B-site

Key Points

• The aim is to enhance the electromagnetic properties of SrFeO3-δ ceramics through Mn doping.
• Synthesize cubic perovskite Sr0.9Y0.1Fe1-xMnxO3-δ ceramics with varying Mn levels (x = 0-0.6).
• Characterize electromagnetic properties and structure changes associated with doping.
• Doping with Mn significantly improves electromagnetic properties compared to undoped samples.
• Optimal Mn concentration at x = 0.4 yielding the best performance metrics.
