A novel A-site ordered quadruple perovskite oxide BiMn3Cr4O12 is prepared using high-pressure and high-temperature techniques, as described in article number 1703435 by Youwen Long and co-workers. Both type-I and type-II multiferroic phases are found to occur in this single-phase compound, giving rise to large ferroelectric polarization and a strong magnetoelectric effect.
