BiFeO3 is a multiferroic materials in which ferroelectric and anti-ferromagnetic orders coexist well above room temperature (TN=643 K, TC=1093 K), with a high polarization (over 100 μC/cm2 [1]).
Using conjugated polymers as the active materials in electronic and optoelectronic devices opens up the possibility of fabricating all-polymer devices using solution processing technologies.
