2.80 to 3.04; y = 1.32 to 1.52; z = 0.54 to 0.64) has five perovskite layers interleaved between (Bi2O2) 2+ fluorite-type layers, while intermixing differing types of A-site (Bi) and B-site (Ti, Mn, Fe) cations within the scaffold drives both ferroelectricity and ferromagnetism within the same structural phase , , . B6TFMO displays saturation magnetization (MS) values of 215 emu/cm 3 (two orders of magnitude larger than BiFeO3) and in-plane saturation polarization (Ps) values of >26 μC/cm 2 . Moreover, B6TFMO demonstrates the reversible linear magnetoelectric switching necessary for practical RT magnetoelectric device applications compatible with low-energy nano-electronics and spintronics , .
