Abstract
Manganese-modified BiFeO3-based ceramics with typical perovskite structure were fabricated by solid-state reaction method with non-quenched processing. The effects of Mn addition on ferroelectric, strain, magnetic properties as well as domain structure were intensively investigated. The average negative strain significantly increased from â¼0.02% to â¼0.10% after Mn incorporation. Piezoresponse force microscope (PFM) analysis revealed that Mn ions can tune ferroelectric domain heavily, and increase the amount of non-180° ferroelectric domain. Raman spectra demonstrated that the formation of ferroelectric domain and enhanced magnetic properties mainly resulted from the strengthened distortion of octahedral due to Mn addition. Our work provides a better understanding of the correlation between the domain structure and macro-properties in Mn-modified BFO-based multiferroic ceramics.
