“…24 Moreover, substitution of La, Nb, and Mn in the BaTiO 3 -BiFeO 3 has been studied in order to enhance the piezoelectric properties and DC resistivity. [25][26][27][28] Recently, improved piezoelectric value of d 33 ¼ 116 pC N À1 with high DC resistivity of 2.7 Â 10 7 X m was reported in Mn-modified BaTiO 3 -BiFeO 3 ceramics by Leontsev et al 28 In parallel, several studies on BaTiO 3 -BiFeO 3 29 Generally, ME effect can be classified as direct magnetoelectric (DME) effect and converse magnetoelectric (CME) effect. The DME effect (dE AC /dH AC ) is defined as the change in electric polarization in response to applied magnetic field.…”

In this paper, single-phase multiferroic ceramics of (1 − x) BaTiO3 − x BiFeO3 (BT − x BFO) were synthesized by solid-solution method in the wide range of material composition (x = 0.025 – 1.0). The changes in crystal structure were confirmed via X-ray diffractions (XRD) and atomic pair distribution functions (PDFs). The room-temperature ME coupling was found to exhibit significant magnitude in the narrow composition window (x = 0.71 – 0.8) where the average crystal structure was found to be rhombohedral. Especially, the BT – 0.725 BFO ceramics containing local monoclinic distortions within rhombohedral phase were found to exhibit high room-temperature ME coefficient (αME) of 0.87 mV/cm·Oe with high piezoelectric properties (g33 = 18.5 × 10 mV m N−1 and d33 = 124 pC N−1). We believe that the high room-temperature ME coupling in single-phase lead-free BT-BFO ceramics provides a possibility of developing electrically or magnetically tunable thin-film devices.

“…As reported in Refs. [5,6, and references therein], rhombohedral symmetry is maintained for x = 0-0.3, after which cubic symmetry predominates up to x = 0.93. For x > 0.93 and for a pure BaTiO 3 compound, the structure is tetragonal.…”

“…Most current investigation tend to destroy the spin cycloid and release the inherent magnetization in order to improve multiferroic properties of BiFeO 3 [4]. This may be achieved, for example, by structural modifi cations or deformations introduced by cation substitution or doping [5]. Therefore, a solid solution of BiFeO 3 [6].…”

Structure and Mössbauer spectroscopy studies of mechanically activated (BiFeO₃)_1−x-(BaTiO₃)_x solid solutions

Abstract. (BiFeO 3 ) 1-x -(BaTiO 3 ) x solid solutions with x = 0.1-0.4 and 0.7 were investigated. The ceramics were prepared by mechanical activation technology and subsequent heat treatment. As was proved by X-ray diffraction, increase of BaTiO 3 concentration causes a change in the crystalline structure from the rhombohedral structure characteristic of BiFeO 3 to a cubic one. 57Fe Mössbauer spectroscopy allowed observation of a gradual transformation from an ordered spin structure of Fe 3+ ions to the paramagnetic state with an increase of x.

“…Bismuth ferrite, BiFeO 3 , is one of such multiferroic materials, in which ferroelectricity and antiferromagnetism coexist at room temperature. The BiFeO 3 has a ferroelectric phase transition temperature, T C ~ 1100 K [3] and antiferromagnetic ordering, with a transition temperature, T N ~ 640 K [4]. BiFeO 3 is known to have a distorted perovskite structure with rhombohedral space group R3c [5] and the spontaneous polarization along the <111> direction.…”

“…The synthesis of BiFeO 3 -BaTiO 3 system is expected to solve the problem of structural instability of bismuth ferrite. The standard method of preparation of BiFeO 3 -BaTiO 3 solid solutions is the solid-state sintering [4,[6][7][8]. Another promising technology is the mechanical activation (MA) as an alternative method of formation of (BiFeO 3 ) 1-x -(BaTiO 3 ) x system with various concentration of barium titanate, x.…”

Effect of BaTiO₃ concentration on structural and magnetic properties of mechanically activated BiFeO₃-BaTiO₃ system

et al. 2017

Abstract. In this research, the mechanical activation method is proposed as an alternative process of preparation of the (BiFeO 3 ) 1-x -(BaTiO 3 ) x solid solutions with various concentrations of barium titanate (x = 0.1÷0.9). However, mechanical milling itself does not allow obtaining the desired products and additional thermal treatment is needed to complete the solid-state reaction. In the present studies, X-ray diffraction and 57 Fe Mössbauer spectroscopy were applied as complementary methods in order to study the structural and magnetic properties of materials. The investigations revealed that an increase of BaTiO 3 concentration causes changes in the crystalline and hyperfi ne magnetic structure of the studied (BiFeO 3 ) 1-x -(BaTiO 3 ) x system.
