A New Class of Room-Temperature Multiferroic Thin Films with Bismuth-Based Supercell Structure

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 res...

Summary: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.
