Intergrowth of two partially miscible phases of BiFeO(3) and BiMnO(3) gives a new class of room-temperature multiferroic phase, Bi(3) Fe(2) Mn(2) O(10+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 BiRO(3) (R = Cr, Mn, Fe, Co, Ni) materials.
两相部分混溶的 BiFeO(3) 和 BiMnO(3) 的交织生长形成了一种新的室温多铁相 Bi(3)Fe(2)Mn(2)O(10+δ)，其具有独特的超晶格 (SC) 结构。SC 异质结构同时表现出室温铁磁性和剩余极化。这些结果为通过控制两种钙钛矿 BiRO(3)（R = Cr、Mn、Fe、Co、Ni）材料的相混合来探索室温单相多铁性薄膜开辟了新途径。
