- Bismuth Ferrite (BiFe03) Description:
1) Bismuth ferrite (BiFeO3), is an inorganic chemical compound with a perovskite structure and an unusual compound of bismuth, iron, and oxygen (BFO). It is one of the most promising lead-free piezoelectric materials, which exhibits multiferroic properties at room temperature.
2) Multiferroic materials exhibit ferroelectric or anti-ferroelectric properties in combination with ferromagnetic (or antiferromagnetic) properties in the same phase. As a result, an electric field can induce change in magnetization and an external magnetic field can induce electric polarization. This phenomenon is known as the magnetoelectric effect (ME) effect and materials exhibiting this effect are called magnetoelectrics or seignetto magnets. Further proof of it being ferromagnetic is that it produces a hysteresis loop during ferroelectric characterization. The ability to couple to either the electric or the magnetic polarisation allows an additional degree of freedom in device designs.
3) However one of the major drawbacks of the material is its high current leakage. Therefore it allows current to pass through when a high voltage is applied. Attempts to improve the electrical properties have been made by doping it with rare earth elements such as lanthanum (La), samarium (Sm), gadolinium (Gd), terbium (Tb) and dysprosium (Dy) etc. The dopant can be at the A site or the B site. A site being the edges of the perovskite cell and the B site being the centre of the perovskite cell.
4) The local short-range magnetic ordering of BiFeO3 is G-type antiferromagnet, that is, each Feþ3 spin is surrounded by six
antiparallel spins on the nearest Fe neighbors.
