“…Введение. Понимание сосуществования структурных фаз является одним из основных принципов для раскрытия механизма пьезоэлектрического отклика, необычного магнитного поведения и физических свойств мультиферроиков со структурой перовскита, таких как BiFeO 3 [1][2][3]. Однофазный BiFeO 3 кристаллизуется в ромбоэдрической структуре R3c, что допускает противофазный октаэдрический наклон и внецентральное смещение катионов вдоль псевдокубического направления [111].…”

The correlation between the multiphase state of the system and its magnetic properties was studied on Bi1–xEuxFeO3 ceramic samples in the range 0.12 ≤ x ≤ 0.18. The X-ray diffraction results indicate that, with an increase in the concentration of Eu ions, a structural transition from the rhombohedral (R3c) to nonpolar orthorhombic (Pnma) phase is observed through the partial formation of an antipolar orthorhombic structure (Pbam). The mixed phase state in the obtained compounds is observed in the range 0.12 ≤ x ≤ 0.16. Magnetic measurements in a strong magnetic field indicate a weak ferromagnetic interaction. The magnetic response in a strong field is explained by the location of the spins at the phase boundary, as well as by the presence of intrinsic antiferromagnetic spins.

In the present work, the BiFeO 3 , Bi 0.9 Ba 0.1 FeO 3 , Bi 0.9 Sm 0.1 FeO 3 , and Bi 0.9 Ba 0.05 Sm 0.05 FeO 3 nanocrystalline thin films on Pt/TiO 2 /SiO 2 /Si (100) substrate are synthesized using the spin coating method, and the structural, morphological, and magnetic properties are systematically investigated. The X-ray diffraction studies reveal that BiFeO 3 , Bi 0.9 Ba 0.1 FeO 3 , and Bi 0.9 Sm 0.1 FeO 3 films exhibit a polycrystalline distorted rhombohedra crystal structure and belong to the R3c space group, whereas, Bi 0.9 Ba 0.05 Sm 0.05 FeO 3 nanocrystalline film has shown a pure rhombohedral crystal structure. The grain size of the films is found to be 86, 75, and 63 nm for Bi 0.9 Ba 0.1 FeO 3 , Bi 0.9 Sm 0.1 FeO 3 , and Bi 0.9 Ba 0.05 Sm 0.05 FeO 3 , respectively. M−H measurements show that the magnetization considerably increases with Ba and Sm doping, and the highest magnetization is found to be 29 and 22 emu cm −3 at 10 and 300 K, respectively, in Bi 0.9 Sm 0.1 FeO 3 film. Further, the blocking temperatures are found to be 100, 150, 130, and 50 K for BiFeO 3 , Bi 0.9 Ba 0.1 FeO 3 , Bi 0.9 Ba 0.05 Sm 0.05 FeO 3 , and Bi 0.9 Sm 0.1 FeO 3 , respectively. IntroductionBiFeO 3 is one of the above room-temperature multiferroic materials, which shows ferroelectric (T C ≈ 830 °C) and magnetic transition (T N ≈ 370 °C) temperatures. This material has been encouraged for the fabrication of non-volatile ferroelectric randomaccess memory, sensors, and microactuators due to the leadfree and environmentally friendly. [1][2][3][4] Nowadays, people are also looking toward photovoltaic [5] and photocatalysis [6] applications. However, this BiFeO 3 has the serious limitation of low magnetic moment and weak magnetoelectric coupling due to the
