They offer an exciting platform for new physics and potentially novel devices. BiFeO$_3$ is one of the most celebrated of multiferroic materials with highly desirable properties. It is the only known room-temperature multiferroic with $T_\\mathrm{C}\\approx 1100~ \\mathrm{K}$ and $T_\\mathrm{N}\\approx 650~\\mathrm{K}$, and exhibits one of the largest spontaneous electric polarisation, $P\\approx 80~\\mu\\mathrm{C/cm}^2$.
