Influence of oxidation number of manganese on magnetic properties of lead free piezoelectric BNT ceramics
Bi0.5Na0.5Ti1-xMnxO3 (x = 0.00, 0.02, 0.05, 0.10, 0.15) ceramics were synthesized by following a solid state reaction route, in which Mn4+ cations were supposed to substitute Ti4+ cations on the B-site. The site occupation and valence fluctuation of Mn2+/3+/4+and Ti3+/4+were characterized by X-ray Photoelectron Spectroscopy (XPS) and Electron Spin Resonance (ESR) for the BNTM-10 ceramics. Magnetization measurements were performed in a Superconducting Quantum Interference Device (SQUID)...[Show more]
