Abstract: | Bismuth ferrite, one of a few multiferroics, has attracted
much attention for many decades since 1960. BiFeO3 (BFO) belongs to
perovskite class of complex oxides. BFO is one of only a few materials in
which (anti)ferromagnetism and ferroelectricity coexis in room temperature. Authors prepared BiFeO3 ceramics by solid state reaction method. The
synthesized powders were characterized by X-ray diffraction method.
Thermogravimetric and differential thermal analysis were investigated. The
microstructure of the BFO ceramics was investigated by means of scanning
transmission electron microscopy, and the ferroelectric characteristic of
BFO ceramics was demonstrated. BFO is very interesting ceramic material for
potential applications in the memory devices, sensors, satellite
communications, optical filters and smart devices. |
