Intergrowth of two partially miscible phases of BiFeO3 and BiMnO3 gives a new class of room-temperature multiferroic phase, Bi3Fe2Mn2O10+δ, which has a unique supercell (SC) structure. The SC heterostructures exhibit simultaneously room-temperature ferrimagnetism and remanent polarization. These results open up a new avenue for exploring room-temperature single-phase multiferroic thin films by controlling the phase mixing of two perovskite BiRO3 (R = Cr, Mn, Fe, Co, Ni) materials.
