“…The ion substitution would influence the inter-strain and tolerance factor. The A-site can be occupied by large cations such as Na + [20], K + [107], Ca 2+ [108], Sr 2+ [46], Ba 2+ [26], Pb 2+ [109], Y 3+ [21], Bi 3+ and Ln (La [27], Nd [22], Sm [23], Gd [24], Ce [110][111][112],Tb [25], Dy [113], Ho [114], Er [115,116], Eu [56], Yb, Th [117], Pr [118]), the B-site can accommodate hetero-valent elements (Ti 4+ , W 6+ [36], Nb 5+ [43], Ta 5+ [119], V 5+ , Cu 2+ [120], Mo 6+ [121], and Mg 2+ [43]) and a variety of magnetic elements (Fe, Cr, Mn, Co, and Ni) [32][33][34][35][36][37][38][39][40][41][42][43][44]52], which will create the possibility of magnetic ordering. More interestingly, the halogen or nitrogen elements substitution on the O-sites was accomplished [122,123].…”

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.

“…APs are promising materials for use in the design and fabrication of high temperature piezoelectric sensors operating under extreme conditions. Moreover, these materials are considered as elements for nonvolatile ferroelectric random-access memory (FeRAM) devices 4,5 and as multifunctional materials that exhibit magnetic properties (multiferroics), 6,7 photoluminescence, [8][9][10] etc. A substantial variability of the composition due to the substitution of A-and B-ions, as well as of the crystal structure due to variations in the number of layers m ¼ 1-6, made it possible to obtain a large number of APs.…”

The structural and electrophysical characteristics of a number of solid solutions of layered oxides of the perovskite-type Bi7[Formula: see text]Wx[Formula: see text][Formula: see text][Formula: see text] ([Formula: see text]) are studied. According to X-ray powder diffraction data, all the compounds studied are single-phase and have the structure of Aurivillius phases ([Formula: see text]) with a rhombic crystal lattice (space group I2[Formula: see text]cm, [Formula: see text]). Changes in tetragonal and rhombic distortions of perovskite-like layers in compounds were considered depending on their chemical composition. The temperature dependences of the relative permittivity [Formula: see text] (T) were measured. It was shown that the Curie temperature [Formula: see text] of the perovskite-type oxides Bi7[Formula: see text]Wx[Formula: see text][Formula: see text][Formula: see text] ([Formula: see text]) linearly decreases with increasing parameter [Formula: see text]. The activation energies of charge carriers were obtained in different temperature ranges. It was found that there are three temperature regions with very different activation energies due to the different nature of the charge carriers in the studied compounds. The effect of substitution of [Formula: see text] ions by [Formula: see text] ions is investigated. It was found that for a number of compounds, the substitution of niobium ions by vanadium ions led to an increase in the dielectric constant and a decrease in the dielectric loss tangent.

The structural and electrophysical characteristics of a series of solid solutions of layered perovs kite type oxides Bi 7 Ti 4 + x W x Nb 1 -2x O 21 (x = 0-0.5) have been investigated. According to X ray powder dif fraction data, all the studied compounds are single phase and have the structure of Aurivillius phases (m = 2.5) with an orthorhombic crystal lattice (space group I2cm, Z = 2). The changes in the tetragonal and orthor hombic distortions of perovskite like layers in the compounds have been considered depending on their chemical composition. The temperature dependences of the relative permittivity ε(T) have been measured. It has been shown that the Curie temperature T C of the perovskite type oxides Bi 7 Ti 4 + x W x Nb 1 -2x O 21 (x = 0-0.5) decreases linearly with an increase in the parameter x. The activation energies of charge carriers have been obtained in different temperature ranges. It has been found that there are three temperature regions with very different activation energies due to different natures of charge carriers in the studied compounds.
