“…При увеличении концентрации самария до 10 % кристаллическая структура BSFO описывается двухфазной моделью: наряду с ромбоэдрической фазой R3c формируется антиполярная орторомбическая Pbam фаза в соотношении ~ 1:1. Для составов с концентрациями x = 0,15 и 0,2 кристаллическая структура BSFO успешно описывается однофазной моделью орторомбической структуры, предполагающей антиполярный характер смещения ионов в A-и B-позициях перовскита [4,5].…”

Исследованы диэлектрические свойства и теплоемкость наноструктурированной керамики мультиферроиков системы Bi 1-x Sm x FeO 3 , полученных методом холодного прессования нанопорошка. Обнаружены сильная дисперсия и острая аномалия диэлектрической проницаемости при 300 °С, а также поддерживаемая магнитодиэлектрической связью аномалия вблизи температуры Нееля. Показано, что замещение висмута самарием приводит к росту диэлектрической проницаемости, заметному смещению и размытию температуры антиферромагнитного фазового перехода, увеличению теплоемкости в широкой области температур. Ключевые слова: BiFeO 3 , наноструктурированная керамика, теплоемкость, диэлектрическая проницаемость.

“…An especially interesting application of SbSI nanowires as well as of other piezoelectric materials as BaTiO 3 (BTO) [ 44 , 45 , 46 , 47 , 48 , 49 ], BiFeO 3 (BFO) [ 50 , 51 , 52 , 53 ], K 0.5 Na 0.5 NbO 3 (KNNO) [ 54 , 55 , 56 ], AlN [ 57 ], and PLZT-based (Pb 1-x La x Zr y Ti 1-y O 3 ) ceramic [ 58 , 59 , 60 , 61 ] are the strain sensors in FRP, due to wide range of its applications in industry. However, proper design of piezoelectric integrated sensors in FRP requires precise interpretation of generated signal and its correlation with structure deformation.…”

In this paper, the performance of epoxy/SbSI nanocomposite under tensile stress was investigated. X-ray diffraction studies show the main stress mode has shear nature in the case of elastic deformation, while a combination of shear and tensile stress during plastic deformation caused lattice deformation of SbSI and shift of sulfur atoms along the c axis of the unit cell. Apart from that, the piezoelectric signals were recorded during tensile tests. Epoxy/SbSI nanocomposite responded to the applied tensile stress by generating a piezoelectric current with a relatively high value. The measured piezoelectric peak-to-peak current is relatively high (Ip-p = 1 pA) in comparison to the current flowing through the sample (8.16 pA) under an applied voltage of 100 V. The current level is independent of the deformation speed rate in contradistinction to complex stress states. The signal comes from the whole volume of the sample between electrodes and is generated by shear stress.

“…Despite having the large spontaneous polarization of bulk BiFeO 3 , the magnetoelectric coupling shows very low value with the absence from quadratic term because the cycloidal modulated spin structure cancels a net magnetization arising from the antisymmetric spin coupling (Dzyaloshinskii-Moriya interaction) inside the G-type antiferromagnetic structure [5]. To overcome this obstacle, recent works have focused on chemical substitution in the Bi-site and Fe-site to collapse the space modulated spin structure [6][7][8]. The substitution of rare-earth elements for BiFeO 3 changes the ferroelectric properties and suppresses the cycloidal spin structure to reveal the weak ferromagnetic behavior [9,10].…”

Effect of Sm and Mn Co-doping on the Crystal Structure and Magnetic Properties of \(\text{BiFeO}_{3}\) Polycrystalline Ceramics

et al. 2020

The crystal structure, phonon vibration, microstructure, and magnetic properties have been investigated in multiferroics Bi0.9Sm0.1Fe1-xMnxO3 for x = 0.02 – 0.1. The structural analysis by XRD and Rietveld refinement suggest that Mn doping compounds crystallize in the polar R3c rhombohedral symmetry (isostructural with BiFeO3). Raman analysis confirms no structural transformation but the change of line widths and peak intensities reveal the lattice distortion in Mn-substitution samples. The study of microstructure shows no obvious change of grain size and shape. The magnetic properties of the as-prepared samples show the linear magnetic field dependence of magnetization, suggesting the antiferromagnetic feature of polycrystalline ceramics. The field dependence of magnetization measured after two-years synthesis and after applying an electric field reveal a decrease of maximum magnetization but the hysteresis loops retain the antiferromagnetic behavior. The implication of these results is that the magnetic properties of single structural phase compound, including coercivity and remanent magnetization, do not show the aging behavior as observed in the morphotropic phase boundary systems.
