"BiFeO3 (or BFO) boasts an impressive resume... including piezoelectricity, ferroelectricity, magnetism, and optical properties... it is one of the very few materials that is magnetoelectric at room temperature, making it viable for use in applications such as future low-energy electronics... It's also lead free, giving it a clear advantage against most high-performing piezoelectric materials... research team pushed BFO into a new phase... allows it to be easily influenced by electric fields"
