The growing modern society demands more new generation devices to fulfil their requirements. This has forced the scientific community to develop multifunctional smart devices. Aurivillius based Bi4Ti3O12 ceramics are one of the leading families of oxide materials, which attract immense attention due to their electrical, ferroelectric, optical, and dielectric properties. These materials have gained special attention due to their numerous device applications such as magnetic recording, sensors, read head technology, spintronic devices, switching devices, data storage devices and multiple state memory devices etc. Multiferroic are the materials in which two or more than two ferroic orders exist simultaneously. This chapter focuses on the possibility of existence of multiferroic behaviour in Aurivillius based compounds specially Bi4Ti3O12. Firstly, we have discussed the basics of multiferroics and their types and the magnetoelectric effect. The effect of different dopants in originating the multiferroism in Bi4Ti3O12 have been reviewed and discuss in detail. At the end comparison of multiferroic and ferrite materials and their future perspective have been discussed.

Single‐phase multiferroic Ba(Fe0.67Ce0.33)0.01Ti0.99O3 (BFTO:Ce) and Ba(Fe0.67La0.33)0.01Ti0.99O3 (BFTO:La) nanostructures were synthesized by a hydrothermal method (180°C/48 h). Rietveld refinement of X‐ray diffraction could confirm crystalline phase and lattice deformation by Ce, La into BFTO. The Ce and La doping induce nanoaggregation‐type BFTO nanostructural product due to their ionic size effect and chemical behavior with OH− ions. Raman active modes show tetragonal phase and defects due to vacancies in the BFTO lattice. Photoluminescence spectrum involves multiple visible emissions due to defects/vacancies. The observed ferroelectric polarization is enhanced due to shape/size effect of nanoparticles, lattice distortion, and filling of d orbital in the perovskite BaTiO3. The room‐temperature magnetic behavior is described due to antiferromagnetic interactions that strengthen by Ce and La doping. The zero‐field cooling and field cooling magnetic measurement at 500 Oe indicates antiferromagnetic to ferromagnetic transition. Dynamic magnetoelectric coupling was investigated, and maximum longitudinal magnetoelectric coefficient is 62.65 and 49.79 mV/cmOe, respectively, measured for BFTO:Ce and BFTO:La. The magnetocapacitance measurements induce negative values that described in terms of magnetoresistance and magnetic phase transition effects. The influence of oxygen vacancy on multiferroicity is evaluated by valance states of O ions.

Owing to decreasing leakage current (La /Sr-doping) and improving magnetic properties (Co-doping), La /Sr and Co co-doped BFTO-n ceramics or films have recently become a focus of attention [139][140][141][142][143], and can show saturated FE hysteresis loops with 2P r~2 0-50 µC/cm 2 and large saturation magnetization with~10 emu/cm 3 for film and~1 emu/g for ceramic.…”

Driven by potentially photo-electro-magnetic functionality, Bi-containing Aurivillius-type oxides of binary Bi4Ti3O12-BiFeO3 system with a general formula of Bin+1Fen−3Ti3O3n+3, typically in a naturally layered perovskite-related structure, have attracted increasing research interest, especially in the last twenty years. Benefiting from highly structural tolerance and simultaneous electric dipole and magnetic ordering at room temperature, these Aurivillius-phase oxides as potentially single-phase and room-temperature multiferroic materials can accommodate many different cations and exhibit a rich spectrum of properties. In this review, firstly, we discussed the characteristics of Aurivillius-phase layered structure and recent progress in the field of synthesis of such materials with various architectures. Secondly, we summarized recent strategies to improve ferroelectric and magnetic properties, consisting of chemical modification, interface engineering, oxyhalide derivatives and morphology controlling. Thirdly, we highlighted some research hotspots on magnetoelectric effect, catalytic activity, microwave absorption, and photovoltaic effect for promising applications. Finally, we provided an updated overview on the understanding and also highlighting of the existing issues that hinder further development of the multifunctional Bin+1Fen−3Ti3O3n+3 materials.
