Bismuth ferrite (BiFeO 3, BFO) exhibits both (anti)ferromagnetic and ferroelectric properties at room temperature. Thus, it has played an increasingly important role in multiferroic system.
The development of bismuth ferrite as a multiferroic nanomaterial is summarized. The morphology, structures, and properties of bismuth ferrite and its potential applications in multiferroic devices with novel functions are presented and discussed. Some perspectives and issues needed to be solved are described.
These materials compromise simultaneous electric and magnetic properties. Ferrite Bismuth (FB) is one of the ceramic materials that enjoy this property and possesses three different crystalline structures (perovskite BiFeO3, selenite Bi 25 FeO 40 and mullite Bi 2 Fe 4 O 9).
Mullite-type bismuth ferrite (Bi2 Fe 4 O 9) as a spin frustrated multiferroic has potential for magnetoelectric coupling, and it might be an appropriate alternative for some of the multiferroics that suffer from a weak magnetoelectric coupling. 1. Introduction The coupling between magnetism and electricity was first understood by Pierre Curie .
Bismuth ferrite (BiFeO 3) is regarded as an important ABO 3 perovskite in the areas of energy storage and electronics. A high-performance novel MgBiFeO 3 -NC nanomagnetic composite (MBFO-NC) electrode was prepared using a perovskite ABO 3 -inspired method as a supercapacitor for energy storage.
Several possible reasons for these phenomena were proposed and discussed. Bismuth ferrite BiFeO 3 is a multiferroic that belongs to the group of materials with a perovskite-type ABO 3 crystal structure. Such crystal structure is formed through a network of corner-linked oxygen octahedra.
